Least-cost allocation of redundancy within subsystems of a series-parallel system to meet a requirement for system reliability may be modelled as a nonlinear integer program in which the number of variables is equal to the number of subsystems. The data are the system requirement...

We evaluate the convolution sums using the theory of quasimodular forms and determine the number of representations of a positive integer n by some direct sum of the forms of discriminant -135 by modular forms. Moreover, we explain how to determine the number of representation...

The main goal of this paper is the investigation of the ε-hyperstability of an Euler-Lagrange type quadratic functional equation f(x + y) +1/2[f(x - y) + f(y - x)] = 2f(y) + 2f(x) in the class of functions from an abelian group into a Banach space.
