The curriculum vitae of Alice Turner Schafer lists two specializations: abstract
algebra (group theory) and women in mathematics. As early as her high school
years Alice exhibited a love for mathematics and an interest in teaching as a
career. As a mathematics educator she championed the full participation of
women in mathematics.
The Eisenstein irreducibility critierion is part of the training of every mathematician.
I first learned the criterion as an undergraduate and, like many before me, was struck
by its power and simplicity. This article will describe the unexpectedly rich history of
the discovery of the Eisenstein criterion and in particular the role played by Theodor
We consider a specialization of an untwisted quantum aﬃne algebra of type ADE at a nonzero complex number, which may or may not be a root of unity. The Grothendieck ring of its ﬁnite dimensional representations has two bases, simple modules and standard modules. We identify entries of the transition matrix with special values of “computable” polynomials, similar to Kazhdan-Lusztig polynomials. At the same time we “compute” q-characters for all simple modules. The result is based on “computations” of Betti numbers of graded/cyclic quiver varieties.

Appendix A. Truncated polynomial algebras References Introduction In this paper we establish a connection between the Quillen K-theory of certain local ﬁelds and the de Rham-Witt complex of their rings of integers with logarithmic poles at the maximal ideal.
