Towards a Characterization of Matrix Monotonicity via Radial Convexity
Małgorzata M. Czerwińska, Jose A. Franco, Allan Merino
The theory of matrix monotone functions of finite degree depends subtly on the matrix size. Motivated by this phenomenon, we introduce radial convexity of metrics with respect to m…
Geometric properties of noncommutative symmetric spaces of measurable operators and unitary matrix ideals
Malgorzata Marta Czerwinska, Anna Kaminska
This is a survey article of geometric properties of noncommutative symmetric spaces of measurable operators , where is a semifinite von Neumann alge…
Banach Envelopes in Symmetric Spaces of Measurable Operators
Malgorzata Czerwinska, Annna Kaminska
We study Banach envelopes for commutative symmetric sequence or function spaces, and noncommutative symmetric spaces of measurable operators. We characterize the class of qu…
k-Extreme Points in Symmetric Spaces of Measurable Operators
Małgorzata M. Czerwińska, Anna Kamińska
Let be a semifinite von Neumann algebra with a faithful, normal, semifinite trace and be a strongly symmetric Banach function space on . We show tha…
