This paper presents (1) a new characterization, via linear programming, of extreme optimal strategies of a matrix game and (2) a simple direct procedure for computing them. The first pertains to the ...

Weighted Sum-Rate Maximization With Transceiver and Passive Beamforming Design for IRS-Aided MIMO-BC Communications via Matrix Fractional Programming ...

We analyze two popular semidefinite programming relaxations for quadratically constrained quadratic programs with matrix variables. These relaxations are based on vector lifting and on matrix lifting; ...
