DESCRIPTION:Classically, complexity theory focuses
  on the hardest instances of a given length. A set
  is in P if there is a decision procedure for it t
 hat runs in polynomial time even on the most diffi
 cult-to-decide instances. Parameterized complexity
  theory, on the other hand, looks at the identific
 ation of easy instances. In this talk, we shall de
 fine parameterizations as independent objects and 
 show that the class of parameterizations naturally
  forms a lattice. The parameterizations that put a
  given set in any of the standard parameterized co
 mplexity classes are filters in this lattice. From
  these insights, we conjecture a separation proper
 ty for P.
