Let M be a compact smooth Riemannian n-manifold with boundary. We combine Gromov’s amenable localization technique the Poincaré duality to study traversally generic geodesic flows on SM, space of spherical tangent bundle. Such generate stratifications governed by rich universal combinatorics. The stratification reflects ways in which flow trajectories are boundary $$\partial (SM)$$ . Specifical...

In our previous publications (IJTAF 2019, Math. Finance 2020), we introduced a general class of SINH-regular processes and demonstrated that efficient numerical methods for the evaluation Wiener-Hopf factors various probability distributions (prices options several types) in L\'evy models can be developed using only few properties characteristic exponent $\psi$. Essentially all popular enjoy th...
