Could anyone please help with these problems?
1. show that the denumerable union of denumerable sets is denumerable.
2. show that for all finite d, N^d is denumerable.
3. Let k be a symmetric convex set in R^p. show that the functional below is a norm.
||x|| subscript k = inf t>= 0 {t: x an element of tk}
Thanks everyone
