We consider the problem of evaluating a functional expression comprising the nested sums and infimal convolutions of convex piecewise-linear functions defined Ε½ . on the reals. For the special case where the nesting is serial, we give an O N log N time algorithm, where N is the total number of break
Let S be the class of functions f z which are analytic and univalent in the open Ε½ . X Ε½ . unit disk U with f 0 s 0 and f 0 s 1. The nth partial sums of the Libera Ε½ . Ε½ . Ε½ . integral operator F z for f z g S are denoted by S z, F . In the present paper, n Ε½ . the starlikeness property of S z, F i
## Abstract The Gamma function and its __n__ th logarithmic derivatives (that is, the polygamma or the psiβfunctions) have found many interesting and useful applications in a variety of subjects in pure and applied mathematics. Here we mainly apply these functions to treat convolutions of the Rayle
