On Maximal Regular Ideals and Identities in the Tensor Product of Commutative Banach Algebras
Let A 1 and A 2 be commutative Banach algebras and A 1 ⊙ A 2 their algebraic tensor product over the complex numbers C. There is always a t least one norm, namely the greatest cross-norm γ ( 2 ), on A 1 ⊙ A 2 that renders it …
