The exact formula for the average hitting time (HT, as an abbreviation) of simple random walks from one vertex to any other vertex on the square $C^2_N$ of an $N$-vertex cycle graph $C_N$ was given by N. Chair [\textit{Journal of Statistical Physics}

In this study, we present two results that relate Tutte polynomials. First, we provide new and complete polynomial invariants for graphs. We note that the number of variables of our polynomials is one. Second, let L_1 and L_2 be two non-isomorphic la

A unit disk graph is a c -strip graph if it has a unit disk representation in which all centers of the unit disks lie between two parallel lines at distance c . The classes of c -strip graphs for various c are studied in the literature. For example,

In this paper, we introduce the concept of the Tutte polynomials of genus $g$ and discuss some of its properties. We note that the Tutte polynomials of genus one are well-known Tutte polynomials. The Tutte polynomials are matroid invariants, and we c

Two n × n ( 0 , 1 ) matrices X , Y are called thin Lehman matrices if they are solutions of the matrix equation XY T = J n + I n , where J n is the n × n matrix of all 1 s and I n is the identity matrix. These matrices are important in the set cove

In 1998, C. Lutolf and F. Margot [C. Lutolf, F. Margot, A Catalog of minimally nonideal matrices, Math. Methods Oper. Res. 47 (1998) 221–241] defined the notion of Lehman matrices in order to classify minimally non-ideal clutters. In the paper [H.

Near and/or 1-overlapped factorizations on cyclic groups play important roles both in perfect graph theory and ideal clutter theory. Such a factorization is Krasner if its construction does not need any modulo operation (i.e. every addition can be th
