Honeycombs and Sums of Hermitian Matrices, Revisited
Ankur Moitra, Alexander Postnikov, Dora Woodruff
We give a new proof of the celebrated theorem of Knutson and Tao that the spectra of triples of Hermitian matrices exactly correspond to positions of boundary rays of h…

Trapezodial property of the generalized Alexander polynomial
Tamás Kálmán, Karola Mészáros, Alexander Postnikov
Fox's conjecture from 1962, that the absolute values of the coefficients of the Alexander polynomial of an alternating link are trapezoidal, has remained stubbornly open to this da…

Affine Weyl groups in K-theory and representation theory
Cristian Lenart, Alexander Postnikov
We give an explicit combinatorial Chevalley-type formula for the equivariant K-theory of generalized flag varieties G/P which is a direct generalization of the classical Chevalley…
