Alfred Goodman Gilman (1941–2015)
On December 23, 2015, Alfred Goodman Gilman died peacefully at home after a long battle with pancreatic cancer. Though Al was one of the great scientific minds of the past 50 years and is best known for his discovery of guanine nucleotide-binding regulatory proteins (G proteins), anyone who trained or worked closely with Al knew him as much more than that. His greatness extended equally to scie...

متن کاملNonstandard Drinfeld-Sokolov reduction
Subject to some conditions, the input data for the Drinfeld-Sokolov construction of KdV type hierarchies is a quadruplet (A,Λ, d1, d0), where the di are Z-gradations of a loop algebra A and Λ ∈ A is a semisimple element of nonzero d1-grade. A new sufficient condition on the quadruplet under which the construction works is proposed and examples are presented. The proposal relies on splitting the...
متن کاملSupersymmetric Drinfeld - Sokolov reduction
The Drinfeld-Sokolov construction of integrable hierarchies, as well as its generalizations, may be extended to the case of loop superalge-bras. A sufficient condition on the algebraic data for the resulting hierarchy to be invariant under supersymmetry transformation is given. The method used is a construction of the hierarchies in superspace, where supersymmetry is manifest. Several examples ...
متن کاملAnd Andrei
A composition of birational maps given by Laurent polynomials need not be given by Laurent polynomials; however, sometimes—quite unexpectedly—it does. We suggest a unified treatment of this phenomenon, which covers a large class of applications. In particular, we settle in the affirmative a conjecture of D. Gale and R. Robinson on integrality of generalized Somos sequences, and prove the Lauren...
