## Abstract In this paper, some optimal inclusion intervals of matrix singular values are discussed in the set Ξ©~__A__~ of matrices equimodular with matrix __A__. These intervals can be obtained by extensions of the Gerschgorinβtype theorem for singular values, based only on the use of positive sca
The present paper deals with discrete approximation on a uniform grid of the first boundary value problem (P C ) for differential inclusions of hyperbolic type. In the form of Euler-Lagrange inclusions, necessary and sufficient conditions for optimality are derived for the discrete (P D ) and contin
