Characterisation of homogenisation for nonlocal diffusion by local topologies
Andreas Buchinger, Krešimir Burazin, Ivana Crnjac +3
We consider fractional variants of divergence form problems with highly oscillatory local coefficients. We characterise the convergence of these coefficients by means of classical…
m-Accretive Extensions of Friedrichs Operators
Krešimir Burazin, Marko Erceg, Sandeep Kumar Soni
The introduction of abstract Friedrichs operators in 2007-an operator-theoretic framework for studying classical Friedrichs operators has led to significant developments in the fie…
Friedrichs systems on an interval
Marko Erceg, Sandeep Kumar Soni
There has been significant developments in the classification of boundary conditions of positive symmetric systems, also known as Friedrichs systems, after the introduction of oper…
The von Neumann extension theory for abstract Friedrichs operators
Marko Erceg, Sandeep Kumar Soni
The theory of abstract Friedrichs operators was introduced some fifteen years ago with the aim of providing a more comprehensive framework for the study of positive symmetric syste…
Evolutionary Equations are -compact
Krešimir Burazin, Marko Erceg, Marcus Waurick
We prove a compactness result related to -convergence for autonomous evolutionary equations in the sense of Picard. Compared to previous work related to applications, we do not…
