The algebraic K-theory of the K(1)-local sphere via TC
Ishan Levy
We describe the algebraic K-theory of the -local sphere and the category of type 2 finite spectra in terms of K-theory of discrete rings and topological cyclic homology. We f…

Adams-type maps are not stable under composition
Robert Burklund, Ishan Levy, Piotr Pstrągowski
We give a simple counterexample to the plausible conjecture that Adams-type maps of ring spectra are stable under composition. We then show that over a field, this failure is quite…

Eilenberg Mac Lane spectra as p-cyclonic Thom spectra
Ishan Levy
Hopkins and Mahowald gave a simple description of the mod Eilenberg Mac Lane spectrum as the free -algebra with an equivalence of and . We s…
