Hi fstal,
linear algebra (matrices, etc.), vector/tensor calculus, or or differential geometry can indeed be used on C4.
Actually, I once found on the internet a thesis about math in combination with c4. It was pretty interesting. Unfortunatey I cannot remember the link but I did save the thesis; I'll give you the header with all necessary info:

Connect-Four

Look it up, it is really interesting, and indeed fstal, there certainly is a way to use linear algebra (matrices, etc.), vector/tensor calculus, or or differential geometry for Connect Four. ;)
