Aiming at the drawback that the shape of Bézier triangles is fixed with respect to the control points,some blending functions with parameter and with similar properties to the bivariate Bernstein polynomials are pres...
Motivated by Problem 164 proposed by Y. Berkovich and E. Zhmud' in their book "Characters of Finite Groups", we give a characterization of finite groups whose irreducible character codegrees are prime powers. This ...

In this paper, we present a robust subneighborhoods selection technique for feature detection on point clouds scattered over a piecewise smooth surface. The proposed method first identifies all potential features usin...
Suppose that G is a planar graph with maximum degree △. In this paper it is proved that G is total-(△ + 2)-choosable if (1) △ ≥ 7 and G has no adjacent triangles (i.e., no two triangles are incident with a c...
