Solution of the system of nonlinear PDEs characterizing CES property under quasi-homogeneity conditions

Advances in Difference Equations, 2021
The constant elasticity of substitution (CES for short) is a basic property widely used in some areas of economics that involves a system of second-order nonlinear partial differential equations.

Geometry of CMC surfaces of finite index

Advanced Nonlinear Studies, 2023
Given r0>0{r}_{0}\gt 0, I∈N∪{0}I\in {\mathbb{N}}\cup \left\{0\right\}, and K0,H0≥0{K}_{0},{H}_{0}\ge 0, let XX be a complete Riemannian 3-manifold with injectivity radius Inj(X)≥r0\hspace{0.1em}\text{Inj}\hspace{0.1em}\left(X)\ge {r}_{0} and with the ...

Differential Geometry of Submanifolds in Complex Space Forms Involving δ-Invariants

Mathematics, 2022
One of the fundamental problems in the theory of submanifolds is to establish optimal relationships between intrinsic and extrinsic invariants for submanifolds.

Geometry and Topology of some overdetermined elliptic problems [PDF]

, 2013
We study necessary conditions on the geometry and the topology of domains in $\mathbb{R}^2$ that support a positive solution to a classical overdetermined elliptic problem. The ideas and tools we use come from constant mean curvature surface theory.

Coarse Geometry and Topological Phases [PDF]

Communications in Mathematical Physics, 2019
We propose the Roe C*-algebra from coarse geometry as a model for topological phases of disordered materials. We explain the robustness of this C*-algebra and formulate the bulk-edge correspondence in this framework. We describe the map from the K-theory of the group C*-algebra of Z^d to the K-theory of the Roe C*-algebra, both for real and complex K ...

Conormal bundles, contact homology and knot invariants [PDF]

, 2006
We summarize recent work on a combinatorial knot invariant called knot contact homology. We also discuss the origins of this invariant in symplectic topology, via holomorphic curves and a conormal bundle naturally associated to the knot.Comment: This is ...

On Canonical Almost Geodesic Mappings of Type π₂(e)

Mathematics, 2020
In the paper, we consider canonical almost geodesic mappings of type π 2 ( e ) . We have found the conditions that must be satisfied for the mappings to preserve the Riemann tensor.

Large Sets in Boolean and Non-Boolean Groups and Topology

Axioms, 2017
Various notions of large sets in groups, including the classical notions of thick, syndetic, and piecewise syndetic sets and the new notion of vast sets in groups, are studied with emphasis on the interplay between such sets in Boolean groups.

Free Boolean Topological Groups

Axioms, 2015
Known and new results on free Boolean topological groups are collected. An account of the properties that these groups share with free or free Abelian topological groups and properties specific to free Boolean groups is given.
