Galois extensions of Lubin-Tate spectra
Andrew Baker, Birgit Richter
Let E_n be the n-th Lubin-Tate spectrum at a prime p. There is a commutative S-algebra E^{nr}_n whose coefficients are built from the coefficients of E_n and contain all roots of u…
Endotrivial modules for the quaternion group and iterated Jokers in chromatic homotopy theory
Andrew Baker
The algebraic Joker module was originally described in the 1970s by Adams and Priddy and is a -dimensional module over the subHopf algebra of the mod Steenr…
Realizability of algebraic Galois extensions by strictly commutative ring spectra
Andrew Baker, Birgit Richter
We discuss some of the basic ideas of Galois theory for commutative S-algebras originally formulated by John Rognes. We restrict attention to the case of finite Galois groups and t…
Asymptotics, Turán inequalities, and the distribution of the BG-rank and 2-quotient rank of partitions
Andrew Baker, Joshua Males
Let be even positive integers, and let denote the number of partitions with BG-rank , and to be the number of partitions with B…
Isogenies of supersingular elliptic curves over finite fields and operations in elliptic cohomology
Andrew Baker
We investigate stable operations in supersingular elliptic cohomology using isogenies of supersingular elliptic curves over finite fields. Our main results provide a framework in w…
Difference-in-Differences Designs: A Practitioner's Guide
Andrew Baker, Brantly Callaway, Scott Cunningham +2
Difference-in-differences (DiD) is arguably the most popular quasi-experimental research design. Its canonical form, with two groups and two periods, is well-understood. However, e…
