Tensor products of C(X)-algebras over C(X)
Résumé
Given a Hausdorff compact space $X$, we study the \mbox{${\rm C}^*$}-(semi)-norms on the algebraic tensor product $A\odot_{C(X)} B$ of two $C(X)$-algebras $A$ and $B$ over $C(X)$. In particular, if one of the two $C(X)$-algebras defines a continuous field of \mbox{${\rm C}^*$}-algebras over $X$, there exist minimal and maximal \mbox{${\rm C}^*$}-norms on $A\odot_{C(X)} B$ but there does not exist any \mbox{${\rm C}^*$}-norm on $A\odot_{C(X)} B$ in general.
