DESCRIPTION:A 3-manifold is called an L-space if its Heegaard Floer homolo
 gy has minimal possible rank.  A link (or knot) is called an L-space link 
 if all sufficiently large surgeries of the three-sphere along its componen
 ts are L-spaces. It is well known that the set of L-space surgeries for a 
 nontrivial L-space knot is a half-line. Quite surprisingly\, even for link
 s with 2 components this set could have a complicated structure. I will pr
 ove that for "most" L-space links (in particular\, for most algebraic link
 s) this set is bounded from below\, and show some nontrivial examples wher
 e it is unbounded. This is a joint work with Andras Nemethi.  <br><br><br>
