Reduced Feynman propagators for Schrödingerized ill-posed dynamics

Schrödingerization maps a non-unitary linear evolution to a unitary dynamics on an enlarged Hilbert space. For ill-posed equations, such as backward diffusion, this does not remove the instability of the recovered physical variable, but it makes the phase-space language of quantum propagation available. We show that th...

Entropy Geometry and Normalized Means on Infinite-Dimensional Hamiltonian Manifolds

We propose a geometric--analytic framework for equilibrium statistical mechanics on infinite-dimensional Hamiltonian systems. In situations where no suitable $\sigma$-additive invariant measure is available, we use \emph{normalized means}, which generalize probability measures and normalized integrals. This constructio...
