%0 Journal Article %T Volume comparison via boundary distances %A Sergei Ivanov %J Mathematics %D 2010 %I arXiv %X The main subject of this expository paper is a connection between Gromov's filling volumes and a boundary rigidity problem of determining a Riemannian metric in a compact domain by its boundary distance function. A fruitful approach is to represent Riemannian metrics by minimal surfaces in a Banach space and to prove rigidity by studying the equality case in a filling volume inequality. I discuss recent results obtained with this approach and related problems in Finsler geometry. %U http://arxiv.org/abs/1004.2505v1
