1.Why the object requires prime number p?
2.Why the padic norm of x is defined by [tex]x_{p}=p^{m}[/tex]([tex]x=\frac{p^{m}r}{s}[/tex]),not [tex]x_{p}=p^{m}[/tex]?
3.[tex]Q_{p}\subset R[/tex] or [tex]R \subset Q_{p}[/tex]?
4.What is the difference between padic and ladic? what is the letter "l" stands for?
