Adaptive Mollifiers for High Resolution Recovery of Piecewise Smooth Data from its Spectral Information
Eitan Tadmor, Jared Tanner
We discuss the reconstruction of piecewise smooth data from its (pseudo-) spectral information. Spectral projections enjoy superior resolution provided the data is globally smooth,…
Detection of Edges in Spectral Data II. Nonlinear Enhancement
Anne Gelb, Eitan Tadmor
We discuss a general framework for recovering edges in piecewise smooth functions with finitely many jump discontinuities, where . Our approach is based…
Spectral Dynamics of the Velocity Gradient Field in Restricted Flows
Hailiang Liu, Eitan Tadmor
We study the velocity gradients of the fundamental Eulerian equation, , which shows up in different contexts dictated by the different modeling of…
Critical Thresholds in Euler-Poisson Equations
Shlomo Engelberg, Hailiang Liu, Eitan Tadmor
We present a preliminary study of a new phenomena associated with the Euler-Poisson equations -- the so called critical threshold phenomena, where the answer to questions of global…
On a new scale of regularity spaces with applications to Euler's equations
Eitan Tadmor
We introduce a new ladder of function spaces which is shown to fill in the gap between the weak spaces and the larger Morrey spaces, . Our motivation for introdu…
