A vertex-colored graph is rainbow vertex-connected if any two ver-tices are connected by a path whose internal vertices have distinct colors, which was introduced by Krivelevich and Yuster.
Covering morphisms of crossed complexes and of cubical omega-groupoids with connection are closed under tensor product

The aim is the theorems of the title and the corollary that the tensor product of two free crossed resolutions of groups or groupoids is also a free crossed resolution of the product group or groupoid...

We show that if a Finsler space is conformally automorphic to a Riemannian space and the automorphism is positively homogeneous with respect to tangent vectors, then the indicatrix of the Finsler spac...
The Connection between the Metric and Generalized Projection Operators in Banach Spaces

In this paper we study the connection between the metric projection operator $P_{K}: B \rightarrow K$, where $B$ is a reflexive Banach space with dual space $B^*$ and $K$ is a non-empty closed convex ...
