Ryszard Engelking

Engelking in 2014

Ryszard Engelking (16 November 1935 – 16 November 2023) was a Polish mathematician. He was working mainly on general topology[1] and dimension theory. He is the author of several influential monographs in this field. The 1989 edition of his General Topology is nowadays a standard reference for topology.[2] Engelking died on 16 November 2023, his 88th birthday.[3]

Scientific work

Apart from his books, Ryszard Engelking is known, among other things, for a generalization to an arbitrary topological space of the "Alexandroff double circle",[4][5] for works on completely metrizable spaces, suborderable spaces and generalized ordered spaces.[6] The Engelking–Karlowicz theorem, proved together with Monica Karlowicz, is a statement about the existence of a family of functions from to with topological[7] and set-theoretical[8] applications.
