 Apr22 comment Fermat's Little Theorem and prime divisors Actually, that is the question, how does it follow. I am told that if follows but can't see why. Apr21 comment Fermat's Little Theorem and prime divisors what do you mean by FMT?

May23 awarded Supporter May23 comment Why is it important that a basis be orthonormal? proximal, yes, indeed. I am asking what is the importance in different subfields in mathematics, physics or others(Fourier Series for example). I suppose that there are people with many different backgrounds and interests here, so if everyone could come up with something, it would be very informative.
