In this paper, we investigate the existence and uniqueness of new almost periodic type solutions, so-called pseudo almost periodic solutions for the systems of
For a kind of L-function of the real quadratic number fields, we prove a Kronecker limit formula which generalized a result of Hecke. And taking an example we g
The paper concerns the formation and construction of shocks. The process of transform from a smooth solution to a shock is precisely described. Meanwhile, the s
