### P-norm

The p-norm of a vector(in 2d) is (|x|^p+|y|^p)^(1/p) my question is can p be 0,fraction or nagetive?

If I recall correctly, p can be any real number apart from 0.

Actually, p must be a real number greater or equal to 1.

### Re: P-norm

Why isn't nagetive number or fractions<1 allowed?

### Re: P-norm

Because it wouldn't be a norm (it would give zero values if any of the coordinates is 0).
