The use of thymineor fluorouracilsubstituted cyclobutanes gave direct access to six-membered ri...

متن کاملAttaching handles to Bryant surfaces
Complete minimal surfaces and constant mean curvature surfaces in Euclidean or hyperbolic space have been the object of much attention in recent years and particular efforts have been devoted in understanding the moduli space of such surfaces. More precisely, the surfaces we are interested in are complete, noncompact surfaces which may or may not be embedded but enjoy the somehow weaker, and sl...
