On MAP Estimates and Source Conditions for Drift Identification in SDEs
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.ABSTRACT We consider the inverse problem of identifying the drift in an stochastic differential equation (SDE) from n$n$ observations of its solution at M+1$M+1$ distinct time points. We derive a corresponding maximum a posteriori (MAP) estimate, we prove differentiability properties as well as a so‐called tangential cone condition for the forward ...

Extremals for Sobolev and exponential inequalities in Hyperbolic space
, 2013 We review results concerning optimal sobolev inequalities in Riemanian manifolds and recent results for sobolev extremals in hyperbolic space. We also presents some existence results for extremals for weighted Moser-Trudinger inequalities in hyperbolic ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract The cratonic lithospheric mantle records complex metasomatic processes and is frequently tapped by alkaline magmatism, offering a unique opportunity to trace the progressive evolution of the mantle. In the present contribution, we investigate a newly identified calc‐alkaline lamprophyre field from the Neoarchean Jonnagiri Schist Belt, Eastern ...

Higher order nonlinear degenerate elliptic problems with weak monotonicity
Electronic Journal of Differential Equations, 2006 We prove the existence of solutions for nonlinear degenerate elliptic boundary-value problems of higher order. Solutions are obtained using pseudo-monotonicity theory in a suitable weighted Sobolev space.

Subduction Parameters Controlling the Occurrence of Shallow and Deep Slow‐Slip Events (SSEs)
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.Abstract Slow‐slip events (SSEs) are transient aseismic fault‐slip phenomena that release tectonic stresses in a variety of tectonic environments, including subduction zones. In subduction margins, SSEs commonly occur along the plate interface at shallow (<20 km) and deep (30–60 km) depths.

On Approximation in Weighted Sobolev Spaces and Self-Adjointness.
MATHEMATICA SCANDINAVICA, 1994 Summary: Necessary and sufficient conditions for approximation by test functions in a type of weighted Sobolev spaces are given. As an application a necessary condition for essential self-adjointness of a perturbed Laplacian is proved. A lemma on the equivalence of two capacities is proved and used to obtain criteria for closability, continuity and ...
