In this paper we prove a zero-free region for L-functions LG(z, x). As an application, an abstract prime number theorem with sharp error-term for formations is
Let Mn be a totally real submanifold in a complex projective space CPn+p.In this paper,we study the position of the parallel umbilical normal vector field of Mn
This article concerded with a semiparametric generalized partial linear model (GPLM) with the type Ⅱ censored data. A sieve maximum likelihood estimator (MLE)
In this paper,auxiliary equation method is proposed for constructing more general exact solutions of nonlinear partial differential equation with the aid of sym
