Transfer principles, Fenchel conjugate and subdifferential formulas in Fan-Theobald-von Neumann systems

Juyoung Jeong, Muddappa Gowda

A Fan-Theobald-von Neumann system is a triple $(V,W,\lambda )$, where $V$ and $W$ are real inner product spaces and $\lambda :V\to W$ is a norm-preserving map satisfying a Fan-Theobald-von Neuma…
