A note on definition of matrix convex functionsWe prove that a real-valued
function f defined on an interval S in R is
matrix convex if and only
Linear conjugation problem with a triangular matrix coefficient, and the construction of the canonical
matrix function is analyzed in detail
Phase representations of the density matrix and quantum distribution functionsA broad class of representations for the density
matrix of phase-space
functions is proposed
Analytical synthesis of functional observers is considered. We propose an algorithm for analytical synthesis of the minimum-order
functional observers based
