Tadeusz Figiel-The Daily Ledger

Tadeusz Figiel (born 2 July 1948 in Gdańsk) is a Polish mathematician specializing in functional analysis.

Biography

In 1970 Figiel graduated in mathematics at the University of Warsaw. He received his doctorate in 1972 under the supervision of Aleksander Pełczyński and then habilitated in 1975 with habilitation thesis O modułach wypukłości i gładkości (On modules of convexity and smoothness) at the (Instytut Matematyczny PAN). There Figiel was appointed in 1983 an associate professor and in 1990 a full professor. He is the head of the Gdańsk Branch of the Polish Academy of Sciences and the editor-in-chief of the journal Studia Mathematica.

Figiel received in 1976 the Stefan Banach Award, in 1988 the of First Degree (together with Zbigniew Ciesielski), in 1989 the , and in 2004 the Stefan Banach Medal. In 1983 he was an Invited Speaker at the International Congress of Mathematicians in Warsaw.
