On the Rate of Convergence of Two Bernstein-Bézier Type Operators for Bounded Variation Functions, II
Xiao-Ming Zeng,Alain Piriou +1 more
TL;DR: In this article, the convergence rates of two Bernstein-Bezier type operators for monotone functions and functions of bounded variation were studied for the case @a>=1.
Journal ArticleDOI
Rate of pointwise approximation for locally bounded functions by Szasz operators
Xiao-Ming Zeng,Alain Piriou +1 more
TL;DR: In this paper, the asymptotic behavior of Szasz operators for locally bounded functions f is studied at points x where f (x + ) and f ( x − ) exist.

Journal ArticleDOI
Hyperbolic conormal spaces and semilinear wave equation
TL;DR: In this article, the authors considered the Cauchy problem for the semilinear wave equation and showed that the nonlinear type singularities of the solution are polynomial with respect to the solution and its first derivatives.
Journal ArticleDOI
On the nonlinear type singularities for semilinear Cauchy problems
TL;DR: Fang et al. as discussed by the authors considered the Cauchy problem for the semilinear wave equation and improved the known results about the nonlinear type singularities of the solution, thanks to the study of multiplicative properties of some refined hyperbolic conormal spaces.
