Wilf Equivalence for the Charge Statistic
Savage and Sagan have recently defined a notion of st-Wilf equivalence for any permutation statistic st and any two sets of permutations $Π$ and $Π'$. In this paper we give a thorough investigation of st-Wilf equivalence for the charge statistic on permutations and use a bijection between the charge statistic and the major index to prove a conjecture ...

Wilf classes of pairs of permutations of length 4
Sn(π1 π2, . . . , πr) denotes the set of permutations of length n that have no subsequence with the same order relations as any of the πi. In this paper we show that Sn(1342, 2143)| = |Sn(3142, 2341)| and Sn(1342, 3124)| = |Sn(1243, 2134)|.

Consecutive pattern containment and c-Wilf equivalence
We offer elementary proofs for several results in consecutive pattern containment that were previously demonstrated using ideas from cluster method and analytical combinatorics. Furthermore, we establish new general bounds on the growth rates of consecutive pattern avoidance in permutations.
