On Divergence-free Drifts
We investigate the validity and failure of Liouville theorems and Harnack inequalities for parabolic and elliptic operators with low regularity coefficients. We are particularly interested in operators of the form ∂t−∆+ b ·∇ resp. −∆+ b ·∇ with a divergence-free drift b. We prove the Liouville theorem and Harnack inequality when b ∈ L∞(BMO) resp. b ∈ BMO−1 and provide a counterexample demonstra...
متن کاملDust “ Drifts ” on Mars
Introduction: Eolian sedimentary deposits are important because they provide a record of the direction and strength of winds on Mars and the type and flux of sediments transported by the winds. While Martian sand dunes and transverse aeolian ridges ("TARs") have been thoroughly studied, the sedimentary deposits left behind by blowing dust have received comparatively little attention to date. Wi...
متن کاملWind-blown flux rates derived from drifts at arctic snow fences
Historically, there has been considerable interest in establishing the relationship between wind-blown snow flux (Q) and wind speed. By monitoring the drift growth at snow fences in Arctic Alaska during three winters, we computed Q for 36 distinct transport events. Each fence was instrumented with depth sounders to measure deposition rates. The majority of events (31) occurred between November ...
متن کاملSome drifts on posets and its application to fuzzy subalgebras
In this paper, given a poset $(X,leq)$, we introduce some drifts on a groupoid $(X,*)$ with respect to $(X,leq)$, and we obtain several properties of these drifts related to the notion of $Bin(X)$. We discuss some connections between fuzzy subalgebras and upward drifts.
