Convexity of the Set of k-Admissible Functions on a Compact Kähler Manifold.
We prove in this article using some convex analysis results of A. S. Lewis the log-concavity of spectral elementary symmetric functions on the space of Hermitian... -
Convexity of Some Spectral Functions on Hermitian Matrices.
We prove in this note the convexity of the functions $u\circ \lambda $ and more generally $u\circ \lambda_B $ on the space of Hermitian matrices, for $B$ a fixed... -
