%0 Journal Article %T Counting function for interior transmission eigenvalues %A Luc Robbiano %J Mathematics %D 2013 %I arXiv %X In this paper we give results on the counting function associated with the interior transmission eigenvalues. For a complex refraction index we estimate of the counting function by Ctn. In the case where the refraction index is positive we give an equivalent of the counting function. %U http://arxiv.org/abs/1310.6273v1
