On the Theory of Surfaces in the Four-dimensional Euclidean Space
Georgi Ganchev, Velichka Milousheva
For a two-dimensional surface in the four-dimensional Euclidean space we introduce an invariant linear map of Weingarten type in the tangent space of the surface, which generates t…

Isogonal Conjugacy and Fermat Problems
Georgi Ganchev, Nikolai Nikolov
We consider three types of isogonal conjugacy of two points with respect to a given triangle and characterize any of these types by a geometric equality. As an application to the F…

Hermitian manifolds of pointwise constant antiholomorphic sectional curvatures
Georgi Ganchev, Ognian Kassabov
In dimension greater than four, we prove that if a Hermitian non-Kaehler manifold is of pointwise constant antiholomorphic sectional curvatures, then it is of constant sectional cu…
