On the tangential cone condition for electrical impedance tomography
arXiv:2105.02635
Abstract
We state some sufficient criteria for the tangential cone conditions to hold for the electrical impedance tomography problem. The results are based on an estimate for the first-order Taylor residual for the forward operator and some convexity results in the Löwner order. As a consequence, for conductivities satisfying certain monotonicity properties, the tangential cone condition is verified.
