On the Tambara Affine Line

David Chan, David Mehrle, J. D. Quigley +2

Tambara functors are the analogue of commutative rings in equivariant algebra. Nakaoka defined ideals in Tambara functors, leading to the definition of the Nakaoka spectrum of prim…

Radicals and Nilpotents in Equivariant Algebra

David Chan, Ben Spitz

Associated to each Tambara functor is its Nakaoka spectrum , analogous to the Zariski spectrum of a commutative ring. We establish that this topological space…

The spectrum of the Burnside Tambara functor

Maxine Elena Calle, David Chan, David Mehrle +3

We compute the spectrum of prime ideals in the Burnside Tambara functor over an arbitrary finite group. Our proof uses recent advances in the commutative algebra of Tambara functor…

The Formal Context of Saturated Transfer Systems on Finite Abelian Groups

Seth Bernstein, Ben Spitz

We describe the reduced formal context of the lattice of saturated transfer systems on a finite abelian group. As an application, we compute that there are 13,784,538,270,571 satur…

-Mackey functors in Macaulay2

Thomas Brazelton, David Chan, Benjamin Mudrak +5

We introduce the CpMackeyFunctors package for Macaulay2, which allows for computations with Mackey functors over a cyclic group of prime order.

Formal Concept Analysis and Homotopical Combinatorics

Scott Balchin, Ben Spitz

Formal Concept Analysis makes the fundamental observation that any finite lattice is determined up to isomorphism by the restriction of the relation ${\leq} \subseteq L…
