A Course in Metric Geometry (Graduate Studies in Mathematics) Dmitri Burago Yuri Burago Sergei Ivanov The top is stained all over. There are stains here and there. The first and last few pages are stained. The text is clean. There were some markings in a few places, which I erased with an eraser. There is a possibility that some marks were missed. This is an old book, so please refrain from purchasing if you are concerned about its condition.
