## Abstract In this paper, we continue to investigate the existence of 4โRGDDs and uniform 5โGDDs. It is proved that the necessary conditions for the existence of such designs are also sufficient with a finite number of possible exceptions. As an application, the known results on the existence of u

In this article, we construct directed group divisible designs (DGDDs) with block size five, group-type h n , and index unity. The necessary conditions for the existence of such a DGDD are n โฅ 5, (n -1)h โก 0 (mod 2) and n(n -1)h 2 โก 0 (mod 10). It is shown that these necessary conditions are also su
## Abstract In this paper the nonlinear viscoelastic wave equation in canonical form equation image with Dirichlet boundary condition is considered. By introducing a new functional and using the potential well method, we show that the damping induced by the viscoelastic term is enough to ensure g
