In this paper we consider the following nonlinear nonlocal Choquard equation F-alpha(u(x) + omega u(x) = C-n,C-2s(vertical bar x vertical bar(2s-n)*u(......

Classification Theorems of Complete Space-Like Lagrangian xi-Surfaces in the Pseudo-Euclidean Space R-2(4)

期刊: BULLETIN OF THE BRAZILIAN MATHEMATICAL SOCIETY, ; ()

xi-submanifolds and xi-translators are, respectively, the natural generalizations of self-shrinkers and translators of the mean curvature flow and, in......

Algebraic Properties of Edge Ideals of Some Vertex-Weighted Oriented m-Partite Graphs

Riemann Problem and Wave Interactions for a Class of Strictly Hyperbolic Systems of Conservation Laws

期刊: BULLETIN OF THE BRAZILIAN MATHEMATICAL SOCIETY, 2020; 51 (4)

A class of strictly hyperbolic systems of conservation laws are proposed and studied. Firstly, the Riemann problem with initial data of two piecewise ......

The Boundedness of Calderon-Zygmund Operators on Lipschitz Spaces Over Spaces of Homogeneous Type

期刊: BULLETIN OF THE BRAZILIAN MATHEMATICAL SOCIETY, 2020; 51 (2)

Let (X,rho,mu) be Ahlfors-1 regular metric spaces. By developing the Littlewood-Paley characterization of Lipschitz spaces over (X,rho,mu) and establi......

Generalizations of Popoviciu's and Bellman's Inequalities

期刊: BULLETIN OF THE BRAZILIAN MATHEMATICAL SOCIETY, 2020; 51 (2)

In the paper, we generalize the well-known Bellman's and Popoviciu's inequalities, and get new Bellman's and Popoviciu's type inequalities. These new ......

On Regularity for the 3D MHD Equations via One Directional Derivative of the Pressure

期刊: BULLETIN OF THE BRAZILIAN MATHEMATICAL SOCIETY, 2020; 51 (1)

This work establishes a new regularity criterion for the 3D incompressible MHD equations in term of one directional derivative of the pressure (i.e., ......

On the Composition Center for a Class of Rigid System
