The next meeting of the Joint Seminar of Analysis, Geometry and Topology Department will be held on November 29, 2016 at 14:00 in Room 478 of IMI.

A talk on:

General Rotational Surfaces in Pseudo-Euclidean 4-Space with Neutral Metric

will be delivered by Yana Aleksieva.

Everybody is invited.

Abstract. We define general rotational surfaces of elliptic and hyperbolic type in the pseudo-Euclidean 4-space with neutral metric which are analogous to the general rotational surfaces of C. Moore in the Euclidean 4-space. We study Lorentz general rotational surfaces with plane meridian curves and give the complete classification of minimal general rotational surfaces, general rotational surfaces with parallel normalized mean curvature vector field, flat general rotational surfaces, and general rotational surfaces with flat normal connection.
