On $C^{\ast }$-norms on ${\mathbb{Z}}_2$-graded tensor products

Vitonofrio Crismale, Stefano Rossi, Paola Zurlo

We systematically investigate $C^{\ast }$-norms on the algebraic graded product of ${\mathbb{Z}}_2$-graded $C^{\ast }$-algebras. This requires to single out the notion of a compatible norm, that…
