Analytic and Algebraic Geometry 4

Opis produktu

This volume (the fourth in the series) is dedicated to two mathematicians: Wojciech Kucharz, who celebrates 70^th anniversary in 2022 and Tadeusz Winiarski who celebrated the 80^th anniversary in 2020. These people were closely associated with our conferences Analytic and Algebraic Geometry. The first one is an active participant of the conferences since 2009 and the second one is a leading figure of the conferences almost from the beginning (1983). Thanks to their mathematical vigor and stimulation the conferences become more interesting and fruitful.
