Abstract

In 1935 Carlitz introduced Bernoulli-Carlitz numbers as analogues of Bernoulli numbers for the rational function field Fr(T)\mathbb F_r(T). In this paper, we introduce Cauchy-Carlitz numbers as analogues of Cauchy numbers. By using Stirling-Carlitz numbers, we give their arithmetical and combinatorial properties and relations with Bernoulli-Carlitz numbers for Fr(T)\mathbb F_r(T). Several new identities are also obtained by using Hasse-Teichim\"uller derivatives.
