| Research Abstract |
We studied special properties of Bernoulli, Genocchi and Stirling numbers of both kinds and discovered new recurrences and higher-order convolution identities. Concerning generalized Frobenuis-Euler numbers and polynomials, we constructed the corresponding L type function after proving basic relations and Kummer type congruences. On the other hand, we discussed new criteria for irregularity of primes and also observed many interesting properties of irregular pairs from numerical experiment.
