A New Iterative Method for Solving General Mixed Variational Inequalities [PDF]

open access: yes, 2008
The general mixed variational inequality containing a nonlinear term φ is a useful and an important generalization of variational inequalities. The projection method cannot be applied to solve this problem due to the presence of the nonlinear term. To

Consistent local projection stabilized finite element methods [PDF]

open access: yes, 2010
This work establishes a formal derivation of local projection stabilized methods as a result of an enriched Petrov-Galerkin strategy for the Stokes problem.

Projection methods and boundary conditions involving the pressure for incompressible viscous flows [PDF]

open access: yes, 2022
We consider a projection method for time-dependent incompressible Navier—Stokes equations with pressure boundary conditions. The projection method is one of the numerical calculation methods for incompressible viscous fluids often used in engineering. In

A local projection stabilization finite element method with nonlinear crosswind diffusion for convection-diffusion-reaction equations [PDF]

open access: yes, 2013
An extension of the local projection stabilization (LPS) finite element method for convection-diffusion-reaction equations is presented and analyzed, both in the steadystate and the transient setting.

A unified approach for regularizing discretized linear ill‐posed problems

open access: yesMathematical Modelling and Analysis, 2009
In this paper we deal with regularization approaches for discretized linear ill‐posed problems in Hilbert spaces. As opposite to other contributions concerning this topic the smoothness of the unknown solution is measured with so‐called approximative ...

Projection methods for integral equations in epidemic

open access: yesMathematical Modelling and Analysis, 2002
In this paper numerical methods for mixed integral equations are presented. Studied equations arise in the mathematical modeling of the spatio‐temporal development of an epidemic.

A Family of Derivative-Free Conjugate Gradient Methods for Constrained Nonlinear Equations and Image Restoration

open access: yesIEEE Access, 2020
In this paper, a derivative-free conjugate gradient method for solving nonlinear equations with convex constraints is proposed. The proposed method can be viewed as an extension of the three-term modified Polak-Ribiére-Polyak method (TTPRP) and ...

Superoperator Master Equations and Effective Dynamics

open access: yesEntropy, 2023
We developed the projection method to derive an analog of the quantum master equation for propagators rather than density matrices themselves. As these propagators are superoperators, we call them superoperator master equations.
