Let M and F each be the set [tex]Z^+[/tex] of all positive integers.So the de Rham Cohomolgoy [tex]H^0(M)[/tex] and [tex]H^0(F)[/tex] is infinite dimensional.(adsbygoogle = window.adsbygoogle || []).push({});

But why does [tex]H^0(M)\otimes H^0(F)[/tex] consist of finite sums of matrices [tex](a_{ij})[/tex] of rank 1?

Thank you!
