ABSTRACT
Let K be a field of characteristic zero, x - an independent variable, E - shift operator with respect to x, i.e. Ef(x) = f(x + 1) for an arbitrary expression f(x). The problem of indefinite summation in general is: given a closed form expression F(x) to find a closed form expression G(x), which satisfies the first order linear difference equation

Accelerating indefinite hypergeometric summation algorithms
Let K be a field of characteristic zero, x an independent variable, E the shift operator with respect to x, i.e., Ef(x) = f(x + 1) for an arbitrary f(x). Recall that a nonzero expression F(x) is called a hypergeometric term over K if there exists a ...
Summation formulae for finite cotangent sums
Recently, a half-dozen remarkably general families of the finite trigonometric sums were summed in closed-form by choosing a particularly convenient integration contour and making use of the calculus of residues. In this sequel, we show that this ...
