DESCRIPTION:Speakers: Chen Zhang (Ruhr University Bochum)\n\nLow-dimension
 al topology seminar\nA long-standing question in knot theory asks whether 
 the set of algebraic knots is linearly independent in the knot concordance
  group\; in other words\, whether every nontrivial linear combination of a
 lgebraic knots fails to be slice. Since a slice knot is necessarily algebr
 aically slice\, a natural refinement of this question is whether an algebr
 aically slice linear combination of algebraic knots must also be smoothly 
 slice. In this talk\, I will introduce an obstruction from Heegaard Floer 
 d-invariants and discuss the techniques for computation.\n\nhttps://math-e
