Inf-sup condition for Stokes with outflow condition
Malte Braack, Thomas Richter
The inf-sup condition is one of the essential tools in the analysis of the Stokes equations and especially in numerical analysis. In its usual form, the condition states that for e…
Mapped coercivity for the stationary Navier-Stokes equations and their finite element approximations
Roland Becker, Malte Braack
This paper addresses the challenge of proving the existence of solutions for nonlinear equations in Banach spaces, focusing on the Navier-Stokes equations and discretizations of th…
Well-posedness of the Stokes problem under modified pressure Dirichlet boundary conditions
Igor Tominec, Josefin Ahlkrona, Malte Braack
This paper shows that the Stokes problem is well-posed when velocity and pressure simultaneously vanish on the domain boundary. This result is achieved by extending Nečas' inequali…
The concept of mapped coercivity for nonlinear operators in Banach spaces
Roland Becker, Malte Braack
We provide a concise proof of existence for nonlinear operator equations in separable Banach spaces. Notably, the operator is not assumed to be monotone. Instead, our main hypothes…
An Adaptive Moving Finite Element Method for Steady Low Mach Number Compressible Combustion Problems
Zhen Sun, Malte Braack, Jens Lang
This work surveys an r-adaptive moving mesh finite element method for the numerical solution of premixed laminar flame problems. Since the model of chemically reacting flow involve…
