# On the integral representation of hermitian definite matrices with negative squares

Plyushсheva V. I.

Abstract

In this article the integral representation of hermitian matrices $F_{j, k}$ $(j, k = 0, ± 1, ...)$ for which all the sums $\sum^n_{j, k = -n} F_{j, k} \xi_j, \xi_k$ have exactly $\mathfrak{x}$ negative squares for large n is given in terms of eigenfunctions of difference equations.
