چکیده
We obtain formulae for group inverses of matrices that are associated with a new class digraphs obtained from stars. This contains both bipartite and non-bipartite graphs. Expressions the inverse corresponding to double star adjacency matrix certain undirected multi-star graphs also proven. A blockwise representation or Dutch windmill graph is presented.

Group inverses of matrices with path graphs
A simple formula for the group inverse of a 2× 2 block matrix with a bipartite digraph is given in terms of the block matrices. This formula is used to give a graph-theoretic description of the group inverse of an irreducible tridiagonal matrix of odd order with zero diagonal (which is singular). Relations between the zero/nonzero structures of the group inverse and the Moore-Penrose inverse of...
متن کاملSymmetry classes of polynomials associated with the dihedral group
In this paper, we obtain the dimensions of symmetry classes of polynomials associated with the irreducible characters of the dihedral group as a subgroup of the full symmetric group. Then we discuss the existence of o-basis of these classes.
متن کاملIntervals of Certain Classes of Z-matrices
Let A and B be M -matrices satisfying A ≤ B and J = [A,B] be the set of all matrices C such that A ≤ C ≤ B, where the order is component wise. It is rather well known that if A is an M -matrix and B is an invertible M matrix and A ≤ B, then aA+ bB is an invertible M -matrix for all a, b > 0. In this article, we present an elementary proof of a stronger version of this result and study correspon...
متن کاملClasses of admissible functions associated with certain integral operators applied to meromorphic functions
In the present paper, by making use of the differential subordination and superordination results of Miller and Mocanu, certain classes of admissible functions are determined so that subordination as well as superordination implications of functions associated with an integral operator hold. Additionally, differential sandwich-type result is obtained.
متن کاملGraph Embeddings, Symmetric Real Matrices, and Generalized Inverses
Graph embedding techniques for bounding eigenvalues of associated matrices have a wide range of applications. The bounds produced by these techniques are not in general tight, however, and may be off by a log n factor for some graphs. Guattery and Miller showed that, by adding edge directions to the graph representation, they could construct an embedding called the current flow embedding, which...
