Person: Iwanik, Anzelm
Anzelm Iwanik was a Polish mathematician who worked on functional analysis, topological dynamics, spectral theory and ergodic theory.
Mathematical Profile (Excerpt):
 In 1972 Iwanik was awarded a Master's degree in mathematics from Wrocław University for his thesis Complete algebras with infinite support.
 Iwanik investigated algebras < A;FA ; FA;F > for which AAA is infinite and FFF contains unary operations only.
 After the award of his Master's thesis in mathematics, which he was awarded with distinction, Iwanik moved from the Institute of Electric Metrology to the Institute of Mathematics remaining in the Technical University of Wrocław.
 With Czeslaw RyllNardzewski as advisor, Iwanik worked on his doctoral dissertation and after submitting his thesis Point realizations of transformation semigroups he was awarded his doctorate in 1974.
 Iwanik was promoted to professor of mathematics at the Technical University of Wrocław in 1990, and full professor in 1996.
 We have already looked at some of Iwanik's early work on universal algebra, semigroups, and the theory of operators on function spaces.
 In the same general area is Iwanik's work on Markov operators published in papers such as On pointwise convergence of Cesaro means and separation properties for Markov operators on C(X)C(X)C(X) (1981) and Unique ergodicity of irreducible Markov operators on C(X)C(X)C(X) (1984).
 By the time this last mentioned paper was published Iwanik was working on topological dynamics.
 Iwanik began working on another topic during the years that he was also working on topological dynamics, namely the spectral theory of measurepreserving transformations.
 For ten years Iwanik jointly ran a seminar at the Institute of Mathematics of the Technical University on ergodic theory.
 Iwanik was a talented teacher who made high demands of his students.
Born 21 April 1946, Tomaszów Mazowiecki, Poland. Died 28 September 1998, Wrocław, Poland.
