On December 30th 2011, the communities of geometric control,
sub-Riemannian geometry and singularity theory lost Vladimir
Zakalyukin. There are no words to express how much we will miss him as a
friend and as a mathematician. I have many pictures of
him. Below you find some of them taken at the Potryagin conference in 2008
and at the Pereslav conference in 2011 (conference for his 60th
birthday) and some other links.
