What is known about discrete versions of the spatially homogenous Boltzmann equation with fi...

Consider a discrete version of spatially homogenous Boltzmann equation with finitely many (but arbitrarily many) velocities $v_i \in \mathbb R^n$ with $i \in I$. Equivalently, consider a system of cou …

What is known about topological equivalence of polynomial dynamical systems on two different...

The question is mainly about $\it flows$, not maps (i.e., continuous time, not discrete time). Is it known if the study of polynomial dynamical systems on $\mathbb R^n$ can be reduced to the study o …

What *piecewise* smooth curves/surfaces/hypersurfaces give rise to forward-invariant regions...

Consider a set $\mathcal{B}\subset \mathbb{R}^n$ that is homeomorphic to a closed n-dimensional ball, and denote its boundary by $\mathcal{H}$. Assume that $\mathcal{H}$ is a "piecewise smooth" hypers …
