@OlivierBégassat Could you clarify what the matrix of a bilinear form is?

@PedroTamaroff Thanks, these are the sort of things I really appreciate in trying to work out how to intuit the topologisation of groups.

Thanks for the thorough answer, and sorry for not replying sooner. The answer has helped understand the theory more, but I still feel confused as to how the author came up with $F(x_1,x_2)$ and $G(x,t)$ in the first line of each proof, their use seems a little magical to me still.

@Travis I don't.
