Krylov improvements of the Uzawa method for Stokes type operator matrices
The paper is devoted to Krylov type modifications of the Uzawa method on the operator level for the Stokes problem in order to accelerate convergence. First block preconditioners and their effect on convergence are studied. Then it ...

Implementation of Numerical Simulation of Viscous Incompressible Flow
The method for solving viscous incompressible flows, based on [1], is presented for the numerical simulation of viscous incompressible flow. It uses a finite element are solved using Uzawa conjugate-gradient algorithms. The goal is ...

Technological Diffusion in the Uzawa-Lucas Model
This paper introduces technological diffusion in the standard Uzawa-Lucas endogenous growth model. We show that the model can be solved analytically in its log-linear approximation. There are three negative eigenvalues, which makes the model...

A Note on the Imbalance Effect in the Uzawa-Lucas Model
The Uzawa-Lucas model is believed to yield a positive dependence of the output growth on the ratio of human capital to physical capital (an empirically plausible imbalance effect). We show that the imbalance effect become less plausible for ...

Adaptive inexact iterative algorithms based on polynomial-degree-robust a posteriori estimates for the Stokes problem
component for algorithms of the Uzawa type. We prove that our estimate gives conforming and conforming stabilized finite element methods on simplicial and rectangular strategies. As example, we choose here the unpreconditioned and ...
