whether a specied real, symmetric matrix is a member of any of several closely related classes: the MMA-matrices; the inverse MMA-matrices; the strictly positive, positive
By a neighbouring system we mean one with coefficients A, G, K, which are arbitrarily close to the given system but have the same symmetries.Thus, strong stability is a form
Theorem 2.2 gives us a representation of matrix R as a product of type (1.2), of t doubly stochastic matrices of simple structure, where t is the cardinality of F.. A

and remarks about the polynomial numerical hulls of order k of normal matrices are given by a new concept “k th roots of a convex set” in section
Also, it is known (see [3]) that any product of n − 1 fully indecomposable stochastic matrices of order n must have all positive entries, so the problem may be restricted to the
These results are used to characterize all extremal weighted trees with the largest p -Laplacian spectral radius among all weighted trees with a given degree sequence and a
The paper is organized as follows: in section 2 reinforced random walks are defined and their representation with urn processes is given.. In section 3 are given the results on
