f((x1....xn)(y1....yn))= (x1....xn)*G*(y1....yn)
where G is the Gram matrix

This is one of several questions you have posted that baffle me!

It is certainly NOT true that every function of two vectors can be written in that way. What conditions are you assuming on f? Is f linear?

In a previous problem you asked for a proof that "Any max isotropic space has dim n". Any vector space has some dimension. What is special about "n" here?
