A Graded Schur Lemma and a graded-monoidal structure for induced modules over graded-commutative algebras
Jürgen Fuchs, Tobias Grøsfjeld
We consider algebras and Frobenius algebras, internal to a monoidal category, that are graded over a finite abelian group. For the case that A is a twisted group algebra in a linea…

Tetrahedral symmetry of 6j-symbols in fusion categories
Jürgen Fuchs, Tobias Grøsfjeld
We establish tetrahedral symmetries of 6j-symbols for arbitrary fusion categories under minimal assumptions. As a convenient tool for our calculations we introduce the notion of a…

Level crossing in random matrices. II Random perturbation of a random matrix
Tobias Grøsfjeld, Boris Shapiro, Konstantin Zarembo
In this paper we study the distribution of level crossings for the spectra of linear families A+lambda B, where A and B are square matrices independently chosen from some given Gau…
