Аннотация
Данная статья посвящена памяти профессора Ковальского, который был одним из ведущих исследователей в области дифференциальной геометрии, особенно римановой и аффинной геометрии. Он внес значительный вклад в повышение уровня преподавания дифференциальной геометрии путем тщательной и систематической подготовки лекций для студентов.
Профессор Ковальский является автором или соавтором более 170 профессиональных статей во всемирно признанных журналах, двух монографий, учебников для студентов.
Профессор Ковальский сотрудничал со многими математиками из других стран (Бельгии, Италии, Японии, Румынии, России, Марокко, Испании и др.).
С уходом профессора Олдржиха Ковальского математическое сообщество теряет значительную личность и исключительного коллегу, доброго и преданного учителя, человека с высокими моральными качествами.
Abstract
This paper is dedicated to the memory of Professor Kowalski who was one of the leading researchers in the field of differential geometry and especially Riemannian and affine geometry. He significantly contributed to raising the level of teaching differential geometry by careful and systematic preparation of lectures for students. Prof. Kowalski is the author or co-author of more than 170 professional articles in internationally recognized journals, two monographs, text books for students. Prof. Kowalski collaborated with many mathematicians from other countries, particularly from Belgium, Italy, Japan, Romania, Russia, Morocco, Spain and others. With the death of Professor Oldřich Kowalský mathematical community are losing a significant personality and an exceptional colleague, a kind and dedicated teacher, a man of high moral qualities.
