Özet
The transcendental p-adic numbers are divided into the three disjoint classes S, T, U and the class U is subdivided into the subclasses Um(m=1,2,3,…) with respect to Mahler’s classification. Using Ruban continued fraction expansions of p-adic Liouville numbers, we prove that integral combinations with algebraic p-adic number coefficients of certain p-adic Liouville numbers are Mahler’s p-adic Um-numbers, where m is the degree of the p-adic algebraic number field determined by these algebraic p-adic number coefficients, and we construct explicit examples to illustrate our results.
