The E_2-term of the K(n)-local E_n-Adams spectral sequence
Heard, Drew Kenneth; Barthel, Tobias (Peer reviewed; Journal article, 2016)Let E=Enbe Morava E-theory of height n. In[8]Devinatz and Hopkins introduced the K(n)-local En-Adams spectral sequence and showed that, under certain conditions, the E2-term of this spectral sequence can be identified with ... -

Landwebers exact functor theorem
Kårstein, Mikkel Elkjær (Bachelor thesis, 2023)Når man jobber med algebraisk topologi bruker man mange invarianter. De er veldig viktige i fagfeltet. En slik invariant er kohomologi. Disse invariantene tar inn topologiske rom og sender ut abelske grupper. Med en passende ... -
Local Gorenstein duality for cochains on spaces
Heard, Drew Kenneth; Barthel, Tobias; Castellana, Natalia; Valenzuela, Gabriel (Peer reviewed; Journal article, 2021)We investigate when a commutative ring spectrum R satisfies a homotopical version of local Gorenstein duality, extending the notion previously studied by Greenlees. In order to do this, we prove an ascent theorem for local ... -
On conjectures of Hovey–Strickland and Chai
Barthel, Tobias; Heard, Drew Kenneth; Naumann, Niko (Peer reviewed; Journal article, 2022)We prove the height two case of a conjecture of Hovey and Strickland that provides a K(n)-local analogue of the Hopkins–Smith thick subcategory theorem. Our approach first reduces the general conjecture to a problem in ... -
On stratification for spaces with Noetherian mod p cohomology
Barthel, Tobias; Castellana, Natalia; Heard, Drew Kenneth; Valenzuela, Gabriel (Peer reviewed; Journal article, 2022)Let $X$ be a topological space with Noetherian mod $p$ cohomology and let $C^*(X;\Bbb{F}_p)$ be the commutative ring spectrum of $\Bbb{F}_p$-valued cochains on $X$. The goal of this paper is to exhibit conditions under ... -
Picard groups and duality for real Morava E–theories
Heard, Drew Kenneth; Li, Guchuan; Shi, XiaoLing Danny (Peer reviewed; Journal article, 2021) -
Rational local systems and connected finite loop spaces
Heard, Drew Kenneth (Peer reviewed; Journal article, 2021)Greenlees has conjectured that the rational stable equivariant homotopy category of a compact Lie group always has an algebraic model. Based on this idea, we show that the category of rational local systems on a connected ... -
The S p k , n –local stable homotopy category
Heard, Drew Kenneth (Peer reviewed; Journal article, 2023) -
Stratification and the comparison between homological and tensor triangular support
Barthel, Tobias; Heard, Drew Kenneth; Sanders, Beren (Peer reviewed; Journal article, 2023)We compare the homological support and tensor triangular support for ‘big’ objects in a rigidly-compactly generated tensor triangulated category. We prove that the comparison map from the homological spectrum to the tensor ... -
Stratification in tensor triangular geometry with applications to spectral Mackey functors
Barthel, Tobias; Heard, Drew Kenneth; Sanders, Beren (Peer reviewed; Journal article, 2023) -
The topological nilpotence degree of a Noetherian unstable algebra
Heard, Drew Kenneth (Peer reviewed; Journal article, 2021)We investigate the topological nilpotence degree, in the sense of Henn–Lannes–Schwartz, of a connected Noetherian unstable algebra R. When R is the mod p cohomology ring of a compact Lie group, Kuhn showed how this invariant ...
