An action principle for dissipative fluid dynamics
… quantum fluctuations. In our formulation, the dynamical degrees of freedom are Stuckelberg-type fields associated to the conserved quantities, which are subject to natural symmetry considerations, and the time evolution of the path integral is along the closed-time contour. Our formulation …

Fluid dynamics in action
… around the classical motion of fluids. The dynamical degrees of freedom are Stuckelberg-like fields associated with diffeomorphisms and gauge transformations, and are related to the conservation of the stress tensor and a U(1) current if the fluid possesses a charge. This inherently …

Pullback of currents by meromorphic maps
My dissertation researches on properties of iterations $f^n=f\circ f\circ \ldots \circ f$ ($n$ times) of a selfmap $f:X\rightarrow X$. Here $X$ is a compact K\"ahler manifold and $f$ is a dominant meromorphic map. For holomorphic maps, a variational principle for smooth maps proves the existence of …
