A 15 second exposure of my field around sunset with the camera resting on a bucket trying to capture the fireflies. I'm going to try again when its darker; I guess it counts as #sliceoflife
#photo #photography

On this cold midwinter night, fire in the fireplace, cup of red wine, good dinner of locally caught mullet with salad from my garden. Life is good even though the world is going to shit. I feel for people in so many places who don't have this warmth, safety, full belly, tonight.

Global existence of weak solutions to a two-phase diffuse interface model of ferrofluids dynamics
Ferrofluids are a class of materials that exhibit both fluid and magnetic properties. We consider a two-phase diffuse interface model for the dynamics of ferrofluids on a bounded domain. One phase is assumed to be magnetic, the other phase can be magnetic or non-magnetic. We derive a coupled system of partial differential equations consisting of the incompressible Navier-Stokes equations, an evolution equation for the magnetization, the magnetostatics equations for the magnetic field and the Ca…

Mon #Kiel,
seit einigen Monaten sehe ich nun keinen Falschparke von Reisswolf mehr in der Legienstraße. Jetzt frage ich mich, ob das wirklich ganz aufgehört hat oder haben die einfach nur ihren Fahrplan geändert und kommen jetzt, wenn ich da nicht zur Arbeit laufe?
Habt ihr was gesehen?

Gab's nicht mal wo Webseiten der #Öffis von #Graz, wo man die "virtuellen" Haltestelleninfos (nächste Abfahrten) von allen Haltestellen online einsehen konnte?
Option 1: wenn ich "Jakominiplatz" eingebe, möchte ich alle derzeitigen (in den kommenden x Minuten) Abfahrten von dor…

On the classification of non-big Ulrich vector bundles on fourfolds
We give an almost complete classification of non-big Ulrich vector bundles on fourfolds. This allows to classify them in the case of Picard rank one fourfolds, of Mukai fourfolds and in the case of Del Pezzo $n$-folds for $n \le 4$. We also classify Ulrich bundles with non-big determinant on Del Pezzo and Mukai $n$-folds, $n \ge 2$.
