Quasi-minimal Rotational Surfaces in Pseudo-Euclidean Four-dimensional Space
Georgi Ganchev, Velichka Milousheva
In the four-dimensional pseudo-Euclidean space with neutral metric there are three types of rotational surfaces with two-dimensional axis - rotational surfaces of elliptic, hyperbo…

Marginally trapped meridian surfaces of parabolic type in the four-dimensional Minkowski space
Georgi Ganchev, Velichka Milousheva
A marginally trapped surface in the four-dimensional Minkowski space is a spacelike surface whose mean curvature vector is lightlike at each point. We introduce meridian surfaces o…
