A generalization of Frenkel's formula
Shmuel Friedland
We generalize Frenkel's integral formula for traces of operators to operators. The resulting formula holds for bounded self-adjoint positive operators and -Schatten class of com…

Tensors, entanglement, separability, and their complexity
Shmuel Friedland
One of the most challenging problems in quantum physics is to quantify the entanglement of -partite states and their separability. We show here that these problems are best addr…

Barrier relaxations of the classical and quantum optimal transport problems
Shmuel Friedland
In the last fifteen years a significant progress was achieved by considering an entropic relaxation of the classical multi-partite optimal transport problem (MPOTP). The entropic r…
