Today, on the ninth day of Vadim Semyonovich's departure, we are giving a page in memory of this great scientist and wonderful man. V.S. Anishchenko's family and friends and Saratov University received many letters and telegrams from scientists, colleagues, and students from all over the world.

A letter from one of Vadim Semenovich's oldest close friends, Werner Ebeling, from the city of Rostock (Germany), says: "We are very excited about the loss of Vadim, an old and unforgettable friend… We will never forget him."

Words of sorrow were received from a long-time close friend and colleague of V.S. Anishchenko, Jurgen Kurths, professor at Humboldt University of Berlin, professor at Saratov University, editor-in-chief of the journal "AIP Chaos: An Interdisciplinary Journal of Nonlinear Science": "I am very shocked by the loss of such a good friend and a great scientist. Vadim had such a wonderful, warm and kind character, and he was always so optimistic and energetic. We will all miss him very much." ("I am so shocked about this, to lose such a good friend and great scientist. Vadim had such a wonderful, warm and kind personality and was always so optimistic and energetic. We all will greatly miss him»).

I received a letter of condolences from Vadim Semenovich's personal friend and colleague Eckehard Schöll, professor at the Technical University of Berlin, the Potsdam Institute for Climate Research: "It is with deep mourning and sorrow that I received this news and would like to express my sincere condolences to the family and your entire (scientific) group in Saratov. I am with you mentally. Vadim was my friend and a great scientist, and we will all miss him very much. I am deeply grateful for many pleasant meetings with him as a friend and as a co-author, as well as for instructive scientific discussions and cooperation." («With deep mourning and grief I have received your message, and I would like to convey my sincerest condolences to the family and to your whole group at Saratov. My thoughts are with you. Vadim was a dear friend and a great scientist, and we will all miss him tremendously. I am deeply grateful for the many pleasant occasions which I had to meet him, as a personal friend and as a collaborator, and for the enlightening scientific discussions and collaborations»).

Personal friend and colleague Dr. Stefano Boccaletti, Director of Science at the Institute of Complex Systems, Florence, Italy, editor-in-chief of the journal "Chaos, Solitons & Fractals" (Elsevier) responded to the death of Vadim Semenovich Anishchenko: "This is terrible news! For me, Vadim was more than just a friend, he did so much for countless people in our environment, including me. I am extremely saddened, and deep in my heart I feel the loss and emptiness that his unexpected death leaves for all of us" ("It is a tremendous news! Vadim was more than a friend for me, and he did so much for a uncountable number of people in our community, including me. I am tremendously sad, and I feel deep in my heart all the sense of loss and vacuum that his unexpected death is leaving to all of us»).

Tomasz Kapitaniak, professor at the University of Technology in Lodz (Poland), a friend and colleague of Vadim Semenovich, expressed his condolences: "I would like to express my sincere condolences to Vadim's wife and daughter and the entire group of nonlinear dynamics in Saratov" ("I would like to express my sincere condolences to You, Vadim's wife and daughter, and to the entire nonlinear dynamics group in Saratov").

The words of condolences came from a long-time personal friend of Vadim Semenovich Vladimir Nikolaevich Belykh, Doctor of Physical and Mathematical Sciences, professor of the Volga State University of Water Transport (Nizhny Novgorod).

In a letter from Associate Professor of Moscow State University, Candidate of Physical and Mathematical Sciences Alexander Vasilyevich Priezzhev, we read: "Terrible news, very sorry, I'm sorry to all my family, friends and colleagues. He was a wonderful man, with whom it was always pleasant and interesting to meet us, Muscovites. I can imagine how hard it is to bear this loss. I bow low. Hold on!"

Students of Vadim Semenovich Anishchenko sent their condolences. Among them are Professor of Ohio State University Alexander Borisovich Neiman, Doctor of Physics at Loughborough University (Great Britain) Natalia Borisovna Yanson and Doctor of Physics Alexander Gennadievich Balanov.

Grigory Bordyugov (Berlin), whose supervisor was Vadim Semenovich in 2000, sent his condolences: "Vadim Semenovich is the person who most influenced the specific turns of my life. In the third year, he absolutely naturally convinced me (and many of my classmates) that it was not only possible to study fundamental science in Russia in the late 90s, but also interesting and promising. He made us part of the department, a collective of young and science-obsessed people. For me, at the age of twenty, the department looked like a very plausible embodiment of NIICHAVO, which seemed to be a privilege to study and work in. Thanks to Vadim Semenovich, I was able to continue doing what I love in Berlin, a city that has become a second homeland for me. Vadim Semenovich knew and endlessly loved Berlin with its complex recent history. He was happy to share this love with many colleagues from Saratov, who came here for the first time with their eyes wide open in surprise. The influence of Vadim Semenovich on my life looks even more implausible when I realize that in fact I didn't spend much time with him directly. And I am well aware that, in addition to mine, Vadim Semenovich has radically changed the fate (certainly for the better, of course!) dozens of other colleagues."

Professor Mikhail Grigoryevich Rosenblum (Potsdam University, Germany) sent his condolences. I received a letter of condolence from Vadim Semenovich's friend and colleague Dr. Astero Provata, from the Laboratory of Statistical Mechanics and Dynamical Systems, the Institute of Nanoscience and Nanotechnology, the National Research Center for Scientific Research "Democritos" (Athens, Greece): "I am deeply touched by this news… He was so full of life and ideas throughout all the conferences we've met at in recent years that it's hard for me to believe it. This is a great loss for Science and an even greater loss for our community. Everyone will miss him. My sincere condolences to his family, friends and colleagues from Saratov and from all over the world" ("I am deeply moved by the news... He was so full of life and ideas in all the conferences we met during the past years, that it is difficult for me to believe it. This is a great loss for Science and a greater one for our community. He will be missed by all. My sincere condolences to his family, friends and colleagues, in Saratov and everywhere»).

From the professor of the Technical University of Berlin and the head of the SFB 910 project Sabine Klapp (Prof. Dr. Sabine Klapp, Technical University Berlin) came this recognition: "Whenever I met Vadim, I was always struck by his kind and friendly nature, scientific foresight and numerous successes. He was a great man whose death creates a big gap. I am with you, his family, his close friends and colleagues. We will miss him" ("Whenever I met Vadim, I was always impressed by his kind-hearted and friendly personality, and by his scientific foresight and his numerous successes. He was a great person, whose death tears a big gap. I feel with you, his family and his close friends and colleagues. We will all miss him»).

Professor Nikolay Vladimirovich Kuznetsov expressed condolences to the family and friends of Vadim Semenovich Anishchenko from the Department of Applied Cybernetics and the Faculty of Mathematics and Mechanics of St. Petersburg State University: "We knew Vadim Semenovich as an outstanding scientist and organizer of science. May the earth rest in peace for him."

All those who came to the Large Physical Audience on the day of farewell to Vadim Semenovich, all those who called during these mourning days spoke of V.S. Anishchenko as an outstanding scientist and a bright person. Rector of the University A.N. Chumachenko emphasized the role of Vadim Semenovich in the development of Saratov University.

The head of the Department of Theoretical Physics of the Faculty of Physics of SSU Lev Mikhailovich Babkov sent his condolences to the relatives and friends of Vadim Semenovich Anishchenko: "What a heavy loss for all of us, his colleagues, the Faculty of Physics, the university... I can't come to terms with the idea that I won't see Vadim Semenovich again... I express my deep condolences to his family, relatives and friends. Colleagues, be healthy, take care of yourself."

For his achievements in scientific and pedagogical activity, V.S. Anishchenko was awarded the medal of the Order of Merit for the Fatherland, II degree (2004), honorary awards of the All-Russian, regional and university ranks. He was awarded the title of "Honorary Professor of Saratov State University named after N.G. Chernyshevsky" (2012).

Many whom he gifted with his selfless help, who were co-authors of his publications, to whom he addressed his scientific reflections, will remember him all their lives. And the university, whose service Vadim Semenovich considered his main purpose, will forever write his name into its glorious history.
