The next meeting of the Joint Seminar of Analysis, Geometry and Topology Department will be held on June 22, 2021, from 11:30 via Zoom.

A talk on:

General Rotational Surfaces in Pseudo-Euclidean 4-Spaces

will be delivered by: Victoria Bencheva.

Everybody is invited.

Abstract. Rotational surfaces are rich source of examples both in Euclidean and pseudo-Euclidean spaces. We consider the so-called general rotational surfaces of elliptic and hyperbolic type in the Minkowski 4-space and the pseudo-Euclidean 4-space with neutral metric which are analogous to the general rotational surfaces introduced by C. Moore in the Euclidean space R^4. We describe analytically some basic subclasses of general rotational surfaces, namely: minimal, flat, with flat normal connection, with parallel normalized mean curvature vector field.
