Title:  Bernoulli-Carlitz numbers and related numbers 

Abstract:   In 1935, L. Carlitz  introduced analogues of Bernoulli numbers for the rational function field , which are called Bernoulli-Carlitz numbers  now.  We introduce Cauchy-Carlitz numbers and Stirling-Carlitz numbers as analogues of Cauchy numbers and Stirling numbers, respectively.  We give several expressions and relations about these numbers.
