A Reduction of the Fractional Calderón Problem to the Local Calderón Problem by Means of the Caffarelli-Silvestre Extension
Giovanni Covi, Tuhin Ghosh, Angkana Rüland +1
We relate the (anisotropic) variable coefficient local and nonlocal Calderón problems by means of the Caffarelli-Silvestre extension. In particular, we prove that (partial) Dirichl…
Is Cosmic Birefringence model-dependent?
Lu Yin, Joby Kochappan, Tuhin Ghosh +1
Exciting clues to isotropic cosmic birefringence have recently been detected in the cross-power spectra of the polarization data of the cosmic microwave background (CMB). Earl…
Effects of Planetesimal Scattering: Explaining the Observed Offsets from Period Ratios 3:2 and 2:1
Tuhin Ghosh, Sourav Chatterjee
The observed deficit and excess of adjacent planet pairs with period ratios narrow and wide of 3:2 and 2:1, the nominal values for the corresponding mean motion resonances (MMRs),…
Fractional anisotropic Calderón problem on closed Riemannian manifolds
Ali Feizmohammadi, Tuhin Ghosh, Katya Krupchyk +1
In this paper we solve the fractional anisotropic Calderón problem on closed Riemannian manifolds of dimensions two and higher. Specifically, we prove that the knowledge of the loc…
The Calderón problem for nonlocal operators
Tuhin Ghosh, Gunther Uhlmann
We study the inverse problem of determining the coefficients of the fractional power of a general second order elliptic operator given in the exterior of an open subset of the Eucl…
An inverse problem for the porous medium equation with partial data and a possibly singular absorption term
Cătălin I. Cârstea, Tuhin Ghosh, Gunther Uhlmann
In this paper we prove uniqueness in the inverse boundary value problem for the three coefficient functions in the porous medium equation with an absorption term $ε\partial_t u-\na…
