A classification of totally F-umbilical submanifolds of an S-manifold
(Soochow University, Department of Mathematics, 1992-04)In this note a classification theorem for totally f-umbilical submanifolds of an S-space form is obtained.

On the connectivity of skeletons of pseudomanifolds with boundary
(Mathematical Institute, Academy of Sciences of the Czech Republic, 2002)In this note we show that 1-skeletons and 2-skeletons of n-pseudomanifolds with full boundary are (n+ 1)-connected graphs and n-connected 2-complexes, respectively. This generalizes previous results due to Barnette and Woon.

Generalized S-space-forms
(2013)We introduce and study generalized S-space-forms. Moreover, we investigate generalized S-space-forms endowed with an additional structure and we obtain some obstructions for them to be S-manifolds

Generalized (κ, µ)-space forms and d-homothetic deformations
(2011)We study the Da-homothetic deformations of generalized (κ, µ)- space forms. We prove that the deformed spaces are again ...
