DESCRIPTION:Abstract: There is a conjectural relationship between Heegaard
  Floer\nhomology and the fundamental group positing that (irreducible) L-s
 paces are\nprecisely  those 3-manifolds with fundamental group that cannot
  be\nleft-ordered. This is known to hold for Seifert fibred spaces\, due i
 n part\nto an interaction of both conditions with (non-existance of)\ntaut
 -foliations. More generally\, for graph manifolds\, work of Boyer and Clay
 \nestablishes an equivalence between taut foliations and left-orderability
 .\nL-spaces I will describe some work in progress with Jonathan Hanselman 
 that\nuses bordered Floer homology to address the still open L-space part 
 of this\nproblem. \n
