HARMONIC NUMBERS OF ORDER TWO

open access: yes, 2012
We investigate sums of Euler type, in particular the summation, in closed form, of the product of Harmonic numbers of order two and the square of reciprocal binomial coefficients. 2000 Mathematics Subject Classification: 05A10; 11B65; 11M06; 33B15; 33D60;

Some binomial sums involving absolute values [PDF]

open access: yes, 2015
We consider several families of binomial sum identities whose definition involves the absolute value function. In particular, we consider centered double sums of the form \[S_{\alpha,\beta}(n) := \sum_{k,\;\ell}\binom{2n}{n+k}\binom{2n}{n+\ell} |k^\alpha-

ON SOME PARTITIONS WHERE EVEN PARTS DO NOT REPEAT

open access: yes, 2009
We offer some new results on some partition functions in which even parts do not repeat. In particular, we show certain partition functions in this category are lacunary.

On Zudilin's q-question about Schmidt's problem

open access: yes, 2012
We propose an elemantary approach to Zudilin's q-question about Schmidt's problem [Electron. J. Combin. 11 (2004), #R22], which has been solved in a previous paper [Acta Arith. 127 (2007), 17--31].

An Ap\'ery-like difference equation for Catalan's constant

open access: yes, 2002
Applying Zeilberger's algorithm of creative telescoping to a family of certain very-well-poised hypergeometric series involving linear forms in Catalan's constant with rational coefficients, we obtain a second-order difference equation for these forms ...
