Coupled Dynamics Between Networks and Fields in Physical Space: A Theoretical Perspective
Networks embedded in physical space often communicate through dynamical fields that both mediate and respond to collective behavior. A unified theoretical perspective is presented for these network‐field systems, linking established mathematical frameworks and revealing how feedback between discrete interactions and continuous spatial processes can ...

ABSTRACT In spatial regression models, unmeasured spatial variables, represented by spatial random effects, are typically not independent of observed covariates and can induce significant bias in covariate effect estimates. This fundamental problem, known as spatial confounding, has been extensively studied, but sometimes with puzzling and seemingly ...

Linear Complementarity Problems over Symmetric Cones: Characterization of Qb-transformations and Existence Results [PDF]
Artículo de publicación ISIThis paper is devoted to the study of the symmetric cone linear complementarity problem (SCLCP). Specifically, our aim is to characterize the class of linear transformations for which the SCLCP has always a nonempty and ...

On the finite termination of an entropy function based smoothing Newton method for vertical linear complementarity problems [PDF]
By using a smooth entropy function to approximate the non-smooth max-type function, a vertical linear complementarity problem (VLCP) can be treated as a family of parameterized smooth equations.

Properties of Classes of Linear Transformations in the Semidefinite Linear Complementarity Problem [PDF]
The semidefinite linear complementarity problem (SDLCP) is ageneralization of the linear complementarity problem (LCP) inwhich linear transformations replace matrices and the cone ofpositive semidefinite matrices replaces the nonnegative orthant.We study

Absolute Value Equation Solution via Dual Complementarity [PDF]
By utilizing a dual complementarity condition, we propose an iterative method for solving the NPhard absolute value equation (AVE): Ax?|x| = b, where A is an n n square matrix.

On the P'2 and P2-properties in the semidefinite linear complementarity problem
Motivated by the so-called P2-property in the semidefinite linear complementarity problems, in this article, we introduce the concept of P2′-property for a linear transformation on the space of real n×n symmetric matrices. While these two properties turn

Formulating and Solving Exhaustible Resource Models as Mixed Complementarity Problems in GAMS [PDF]
In this paper a formulation of dynamic non-linear programs as mixed complementarity problems (mcp) is shown. Models of exhaustible resource markets are used to describe the transformation.
