Reconstruction of rough potentials in the plane
Jorge Tejero
We provide a reconstruction scheme for complex-valued potentials in for . The procedure extends the method of Bukhgeim relying on quadratic exponential…
Uniqueness in the inverse conductivity problem for complex-valued Lipschitz conductivities in the plane
Evgeny Lakshtanov, Jorge Tejero, Boris Vainberg
We consider the impedance tomography problem in the plane. Using Bukhgeim's scattering data for the Dirac problem, we prove that the conductivity is uniquely determined by the Diri…
Reconstruction and stability for piecewise smooth potentials in the plane
Jorge Tejero
We show that potentials with jump discontinuities can be recovered from the Dirichlet-to-Neumann map using Bukhgeim's method. Combining with known formulas, this enables the recove…
Maximum Likelihood Estimation of the correlation parameters for elliptical copulas
Lorenzo Hernández, Jorge Tejero, Jaime Vinuesa
We present an algorithm to obtain the maximum likelihood estimates of the correlation parameters of elliptical copulas. Previously existing methods for this task were either fast b…
Percentiles of sums of heavy-tailed random variables: Beyond the single-loss approximation
Lorenzo Hernández, Jorge Tejero, Alberto Suárez +1
A perturbative approach is used to derive approximations of arbitrary order to estimate high percentiles of sums of positive independent random variables that exhibit heavy tails.…
