ABSTRACT:

In this note, we have obtained some novel results on trilateral generating functions involving Ynalpha+nk (x; k), a modified form of Konhauser biorthogonal polynomials, {Ynalpha (x; k)} with Tchebycheff polynomials by group theoretic method. As special cases, we have obtained the corresponding results on Lagurrepolynomials.

ABSTRACT:

In this paper, we will obtain if A is a q-k-normal matrix and B is any matrix close to A, then the optimal matching distance

d(sigma (A),sigma(B)) is bounded by || A-B||.
