Positive-off-diagonal Operators on Ordered Normed Spaces and Maximum Principles for M-Operators
… that its (positive) inverse satisfies certain maximum principles? We deal with generalizations of the "maximum principle for inverse column entries".

Topics in harmonic analysis and partial differential equations: extension theorems and geometric maximum principles
… used to obtain a sharp version of Hopf's Strong Maximum Principle for second-order, non-divergence form differential operators with singular drift. This part of my thesis originates from a recent paper in collaboration with D. Brigham, V. Maz'ya, M. Mitrea, and E. Ziad e.

On Enforcing Maximum Principles and Element-Wise Species Balance for Advective-Diffusive-Reactive Systems
… mathematical properties like comparison principles, maximum-minimum principles, non-negativity, and monotonicity of the solution. It is desirable and in many situations necessary for a predictive numerical solver to meet important physical constraints. For example, a negative value for …

Análise limite de cascas via otimização
… theorems are established as minimum and maximum principles. The plastic collapse theorems are applied to develop static and kinematic numerical methods for the limit analysis of shells of revolution. Both methods involve finite element discretization and solving linear programming …

Qualitative Properties Of Solutions Of Fully Nonlinear Equations And Overdetermined Problems
<p>In section 2 of part I, We study the maximum principles and radial symmetry for viscosity solutions of fully nonlinear partial differential equations. We</p> <p>obtain the radial symmetry and monotonicity properties for</p> <p>nonnegative viscosity solutions of fully nonlinear equations under …

On Steady Water Waves and Their Properties
Abstract: This thesis consists of four papers related to various aspects of steady water waves. Paper I: Deep-water waves with vorticity: symmetry and rotational behaviour. We show that for steady, periodic, and rotational gravity deep-water waves, a monotone surface profile between troughs and …

Structure-Preserving High Performance Computational Methods for Transport in Porous Media
… diffusion (i.e., they violate dis- crete maximum principles) and the inability of the standard finite element formulation to ensure local mass balance. Moreover, there is no platform-agnostic performance model that can simultaneously document both the hardware/architectural and algo- …

Visibility and argument identification : a conceptual semantic approach to Alamblak and Japanese
… relationship between syntax and semantics with maximum principles and minimum stipulations. The main concepts of the theory are argument identification and visibility. First, I introduce binary conceptual structure, whereby the hierarchical relationship among conceptual arguments is structurally …
