“…One could also ask for a classification of the thick tensor-ideals of dualizable objects in Sp k,n , or equivalently a computation of the Balmer spectrum Spc(Sp dual k,n ). Based on a conjecture of Hovey and Strickland, the author, along with Barthel and Naumann, investigated Spc(Sp dual K(n) ) in detail in [BHN20], showing that the Hovey-Strickland conjecture holds when n = 1 and 2, and that in general it is implied by a hope of Chai in arithmetic geometry. In this section, we make some general comments regarding Spc(Sp dual k,n ).…”

Following a suggestion of Hovey and Strickland, we study the category of K(k) ∨ K(k +1)∨• • •∨K(n)-local spectra. When k = 0, this is equivalent to the category of E(n)-local spectra, while for k = n, this is the category of K(n)-local spectra, both of which have been studied in detail by Hovey and Strickland. Based on their ideas, we classify the localizing and colocalizing subcategories, and give characterizations of compact and dualizable objects. We construct an Adams type spectral sequence and show that when p ≫ n it collapses with a horizontal vanishing line above filtration degree n 2 + n − k at the E 2 -page for the sphere spectrum. We then study the Picard group ofshowing that this group is algebraic, in a suitable sense, when p ≫ n. We also consider a version of Gross-Hopkins duality in this category. A key concept throughout is the use of descent. Contents1. Introduction 1 2. The category of Sp k,n -local spectra 4 3. Thick subcategories and (co)localizing subcategories 8 4.

We begin by introducing some of the main spectra that we will be interested in.2.1. Definition. Let BP denote the Brown-Peterson ring spectrum with coefficient ring2.2. Remark. The generators v i are not well-defined; for example they could be the Hazewinkel generators or the Araki generators. However, the ideals I n = (p, v 1 , . . . , v n−1 ) for 0 ≤ n ≤ ∞ are well-defined.By taking quotients and localizations of BP (for example, using the theory of structured ring spectra [EKMM97, Chapter V]), we can form new ring spectra. In particular, let J k denote a fixed invariant regular sequence p i0 , v i1 1 , . . . , v i k−1 k−1 of length k. Then we can form the associative ring spectrum BP J k with (BP J k ) * ∼ = BP * /J k .

“…Hovey and Strickland have conjectured a description of the Balmer spectrum Spc(Sp dual K(n) ) of dualizable objects in K(n)-local spectra. This was investigated by the author, along with Barthel and Naumann,in [BHN20]. This admits a natural generalization to Sp dual k,n .…”
