In this article,we consider endomorphism algebras of direct sums of some local left ideals over a local algebra and give a construction of quasi-hereditary alge
The aim of this paper is to study numerical realization of the conditions of Max Nther’s residual intersection theorem. The numerical realization relies on o
Let G be a simple graph and let Q(G) be the signless Laplacian matrix of GIn this paper we obtain some results on the spectral perturbation of the matrix Q(G) u
