Zbigniew Ciesielski

Zbigniew Ciesielski (1 October 1934 – 5 October 2020[1]) was a Polish mathematician, specializing in functional analysis and probability theory.

Zbigniew Ciesielski

Ciesielski was born in Gdynia, Poland. He received in 1960 his doctorate from the Adam Mickiewicz University in Poznan with dissertation O rozwinięciach ortogonalnych prawie wszystkich funkcji w przestrzeni Wienera (On orthogonal developments of almost all functions in Wiener space) under the supervision of Władysław Orlicz.[2]

He has been a professor at the Mathematical Institute of the Polish Academy of Sciences since 1969 and a member of the Academy since 1973. In 1974 he was an Invited Speaker of the International Congress of Mathematicians in Vancouver.[3][4] He was president of the Polish Mathematical Society from 1981 to 1983.

Ciesielski's main areas of research are functional analysis, in particular Schauder bases in Banach spaces, and probability theory, in particular the mathematical theory of Brownian motion.
