Bijective evaluation of the connection coefficients of the double coset algebra
Alejandro H. Morales, Ekaterina A. Vassilieva
This paper is devoted to the evaluation of the generating series of the connection coefficients of the double cosets of the hyperoctahedral group. Hanlon, Stanley, Stembridge (1992…
Matrices with restricted entries and q-analogues of permutations
Joel Brewster Lewis, Ricky Ini Liu, Alejandro H. Morales +3
We study the functions that count matrices of given rank over a finite field with specified positions equal to zero. We show that these matrices are -analogues of permutations w…
E7(7) constraints on counterterms in N=8 supergravity
Niklas Beisert, Henriette Elvang, Daniel Z. Freedman +3
We prove by explicit computation that 6-point matrix elements of D^4R^4 and D^6R^4 in N=8 supergravity have non-vanishing single-soft scalar limits, and therefore these operators v…
