Alex Chigogidze

Alexander Chigogidze (; 1 January 1955 – 14 December 2014) was a Georgian-born general topologist. Chigogidze is best known for his book ''Inverse Spectra'', in which he passed on to the next generation of topologists the results of the Fedorchuk -Schepin Topology seminars held at the Moscow State University during the 1980s. The book also contains important contributions Chigogidze made in the area of General Topology and Geometric Topology (of Bing-Borsuk type). In the area of General Topology, Chigogidze developed extension theory for noncompact nonmetrizable spaces. In the area of Geometric Topology, Chigogidze introduced grading to shape theory by developing a theory n-Shape where n is an arbitrary integer. This was a major addendum to the existing n-Homotopy theory.

After graduating from Tbilisi State University, he became a research associate at Moscow University, moved on to become an associate professor and full professor at the University of Saskatchewan (Canada), and at the University of North Carolina at Greensboro where he was the H.Barton Excellence Professor and served as Head of the Mathematics Department. He served as the Dean of Science & Technology at the City University of New York, College of Staten Island.

Throughout his mathematical career, he published over 100 papers and two books. Provided by Wikipedia
