A remark on a paper by Alessandrini and Vessella

We prove that the Lipschitz constant of the Lipschitz stability result for the inverse conductivity problem proved in [G. Alessandrini, S. Vessella, Lipschitz stability for the inverse conductivity problem, Adv. in Appl. Math. 35 (2005) 207-241], behaves exponentially with respect to the number N of regions considered.
