Pretzel knots with L-space surgeries (1306.6707v1)
Published 28 Jun 2013 in math.GT
Abstract: A rational homology sphere whose Heegaard Floer homology is the same as that of a lens space is called an L-space. We classify pretzel knots with any number of tangles which admit L-space surgeries. This rests on Gabai's classification of fibered pretzel links.
