Springer varieties are studied because their cohomology carries a natural action of the symmetric group Sn and their top-dimensional cohomology is irreducible. In his work on tangle invariants, Khovanov constructed a family of Springer varieties Xn as subvarieties of the product of spheres (S). We show that if Xn is embedded antipodally in (S) then the natural Sn-action on (S) induces an Sn-rep...

What are the factors that influence everyday attributions of cause and blame? The current studies focus on sequences of events that lead to adverse outcomes, and examine people's cause and blame ratings for key events in these sequences. Experiment 1 manipulated the intentional status of candidate causes and their location in a causal chain. Participants rated intentional actions as more causal...

Counterexample-guided abstraction refinement (CEGAR) is a property-directed approach for the automatic construction of an abstract model for a given system. The approach learns information from infeasible error paths in order to refine the abstract model. We address the problem of selecting which information to learn from a given infeasible error path. In previous work, we presented a method th...
