摘要：

We show that bright solitary waves of different topologies can exist in a discrete system with a quadratic nonlinearity. Analytical solutions can be derived for a limiting case. The regions of existence and stability are identified. We numerically study interaction and collision phenomena. Various decay scenarios for unstable solutions are discussed.
