On the solvability of general cubic equations over ℤp*

Mansoor Saburov*, Mohd Ali Khameini Ahmad

ABSTRACT:     The p-adic models of statistical mechanics require an investigation of the roots of polynomial equations over p-adic fields in order to construct p-adic Gibbs measures. The most frequently asked question is whether a root of a polynomial equation belongs to some given domains. In this paper, we study the solvability of general cubic equations over ℤp* where prime p>3. Our investigation enables us to describe all translation invariant p-adic Gibbs measures on a Cayley tree of order three.
