作者：Michael Aschbacher 来源：[J].Memoirs of the American MathematicalSociety(IF 1.821), 2019, Vol.257 (1236)AMS 摘要：This memoir begins a program to classify alarge subclass of the class of simple saturated 2-fusion systemsof component type. Such a classification would be of greatinterest in its own right, but in addition it should lead to asignificant simplification of the proof of the th...

In this paper, we correct an error in a proof of a theorem of Se...

Yuditskii 来源：[J].Transactions of the American Mathematical Society, Series B, 2019, Vol.6 (1), pp.1-44AMS 摘要：We establish precise spectral criteria for potential functions $V$ of reflectionless Schrödinger operators $L_V = -\partial _x^2 + V$ to admit solutions to the Korteweg-de Vries (KdV) hierarchy with $V$ as an initial value. More generally, our methods extend the classical...

Lusztig 来源：[J].Representation Theory of the American Mathematical Society, 2018, Vol.22 (9), pp.246-277AMS 摘要：Let $X$ be the group of weights of a maximal torus of a simply connected semisimple group over $\mathbf {C}$ and let $W$ be the Weyl group. The semidirect product $W((\mathbf {Q}\otimes X)/X)$ is called an extended Weyl group. There is a natural $\mathbf {C}(v)$-algebra \$ \m...

The main idea concerns compatibility , the fitting together of the phases of a material. Some of the emerging materials have the ability to change heat directly into el...
