amenability isoperimetric constant embeddings into Hilbert spaces
2012/5/24
We define the isoperimetric constant for any locally finite metric space and we study the property of having isoperimetric constant equal to zero. This property, called Small Neighborhood property, cl...
Classification of nonorientable regular embeddings of Hamming graphs
Graph embeddings regular embeddings regular map Hamming graphs

Abstract: By a regular embedding of a graph K in a surface we mean a 2-cell embedding of K in a compact connected surface such that the automorphism group acts regularly on flags. In this paper, we cl...
