Separating multilinear branching programs and formulas
This work deals with the power of linear algebra in the context of multilinear computation. By linear algebra we mean algebraic branching programs (ABPs) which are known to be com...

On the Rate Duality of MIMO Interference Channel and Its Application to Sum Rate Maximization
In this paper, we establish a rate duality between the forward and reverse links of MIMO interference channel, where the reverse links are obtained by exchanging the roles of trans...

Asymptotic expansions for a class of tests for a general covariance structure under a local alternative
Let S be a p × p random matrix having a Wishart distribution Wp(n, n−1Σ). For testing a general covariance structure Σ = Σ(ξ), we consider a class of test statistics Th = n...
