Reichenbach's Common Cause Principle in Algebraic Quantum Field Theory with Locally Finite Degrees of Freedom
Gábor Hofer-Szabó, Péter Vecsernyés
In the paper it will be shown that Reichenbach's Weak Common Cause Principle is not valid in algebraic quantum field theory with locally finite degrees of freedom in general. Namel…

Larson-Sweedler Theorem and the Role of Grouplike Elements in Weak Hopf Algebras
P. Vecsernyes
We extend the Larson-Sweedler theorem to weak Hopf algebras by proving that a finite dimensional weak bialgebra is a weak Hopf algebra iff it possesses a non-degenerate left integr…

S_4-symmetry of 6j-symbols and Frobenius-Schur indicators in rigid monoidal C^*-categories
J. Fuchs, A. Ch. Ganchev, K. Szlachanyi +1
We show that a left-rigid monoidal C^*-category with irreducible monoidal unit is also a sovereign and spherical category. Defining a Frobenius-Schur type indicator we obtain selec…
