On well-f-coveredness of lexicographic product of graphs
Reza Jafarpour-Golzari
A simple graph G is said to be well-f-covered, whenever any two maximal induced forest in G be of the same order. In this note, well-f-coveredness of lexicographic product of two g…
Graphs whose all maximal induced forests are of the same order
Reza Jafarpour-Golzari
In this paper, a new concept in graphs namely well-f-coveredness is introduced. We characterize all graphs with such property, whose maximum induced forests are of boundary order.…
Degree polynomial of vertices in a graph and its behavior under graph operations
Reza Jafarpour-Golzari
In this paper, we introduce a new concept namely degree polynomial for vertices of a simple graph. This notion leads to a concept namely degree polynomial sequence which is stronge…
A generalization of hall's theorem for k-uniform k-partite hypergraphs
Reza Jafarpour-Golzari
In this paper we prove a generalized version of Hall's theorem for hypergraphs. More precisely, let H be a k-uniform k- partite hypergraph with some ordering on parts as V1, V2,...…
Unmixed d-uniform r-partite hypergraphs
Reza Jafarpour-Golzari, Rashid Zaare-Nahandi
In this paper, we characterize all unmixed d-uniform r-partite hypergraphs under a certain condition. Also we give a necessary condition for unmixedness in d-uniform hypergraphs wi…
-Metrics and -Metric Spaces
Reza Jafarpour-Golzari
In this paper, we define notions of -metric and -metric space and we show that every -metric Space, analogous to an ordinary metric space and generall…
