Abstract:
In this paper we use the Euler-Seidel method for deriving new identities for hyperharmonic and r-Stirling numbers. The exponential generating function is determined for hyperharmonic numbers, which result is a generalization of Gosper’s identity. A classification of second order recurrence sequences is also given with the help of this method.
Keywords:Harmonic numbers  Hyperharmonic numbers   r-Stirling numbers  Fibonacci numbers  Euler-Seidel matrices
