  • A Whirlwind Tour of the World of (∞,1)-Categories
    Contemporary Mathematics A Whirlwind Tour of the World of (1; 1)-categories Omar Antol´ınCamarena Abstract. This introduction to higher category theory is intended to a give the reader an intuition for what (1; 1)-categories are, when they are an appro- priate tool, how they fit into the landscape of higher category, how concepts from ordinary category theory generalize to this new setting, and what uses people have put the theory to. It is a rough guide to a vast terrain, focuses on ideas and motivation, omits almost all proofs and technical details, and provides many references. Contents 1. Introduction 2 2.

Edited Version. c 2017 { David Lukas Benjamin Brantner All rights reserved. Jacob Lurie David Lukas Benjamin Brantner The Lubin-Tate Theory of Spectral Lie Algebras Abstract We use equivariant discrete Morse theory to establish a general technique in poset topology and demonstrate its applicability by computing various equivariant properties of the partition complex and related posets in a uniform manner. Our technique gives new and purely combinatorial proofs of results on algebraic and topological Andr´e-Quillenhomology. We then carry out a general study of the relation between monadic Koszul duality and unstable power operations. Finally, we combine our techniques to compute the operations which act on the homotopy groups K(n)-local Lie algebras over Lubin-Tate space. iii Contents 1 Statement of Results 4 1.1 Discrete Morse Theory and the Partition Complex . .4 1.2 Background on Operations . .9 1.3 Intertwining Algebraic and Topological Koszul Duality . 13 Cpl(I) 1.4 Operations on Lie Algebras in ModE .............................. 14 2 Discrete Morse Theory and the Partition Complex 18 2.1 Preliminaries . 18 2.2 Complementary Collapse . 23 2.3 Young Restrictions . 30 2.4 Fixed Points . 39 2.5 A Colimit Decomposition for G-Spaces . 41 2.6 Strict Quotients and Commutative Monoid Spaces . 49 3 Intertwining Topological and Algebraic Koszul Duality 55 3.1 Operations on the (co)Homotopy of (co)Algebras .

Classically, two polytopes in a manifold X are defined to be scissors congruent if they can be decomposed into finite sets of pairwise-congruent polytopes. We generalize this notion to an abstract problem: given a set of objects and decomposition and congruence relations between them, when are two objects in the set scissors congruent? By packaging the scissors congruence information in a Waldhausen category we construct a spectrum whose homotopy groups include information about the scissors congruence problem. We then turn our attention to generalizing constructions from the classical case to these Waldhausen categories, and find constructions for cofibers, suspensions, and products of scissors congruence problems.

  • On the Unicity of the Homotopy Theory of Higher Categories
    ON THE UNICITY OF THE HOMOTOPY THEORY OF HIGHER CATEGORIES CLARK BARWICK AND CHRISTOPHER SCHOMMER-PRIES Abstract. We propose four axioms that a quasicategory should satisfy to be considered a reasonable homotopy theory of (1; n)-categories. This axioma- tization requires that a homotopy theory of (1; n)-categories, when equipped with a small amount of extra structure, satisfies a simple, yet surprising, uni- versal property. We further prove that the space of such quasicategories is homotopy equivalent to (RP1)n. In particular, any two such quasicategories are equivalent. This generalizes a theorem of To¨enwhen n = 1, and it veri- fies two conjectures of Simpson. We also provide a large class of examples of models satisfying our axioms, including those of Joyal, Kan, Lurie, Rezk, and Simpson. 1. Introduction The chaotic prehistory of higher category theory, whose origins can be traced to an assortment of disciplines, has borne a diverse subject with a range of appara- tuses intended to formalize the imagined common themes in the notions of operad, monoidal category, n-category, homotopy algebra (of various flavors), higher stack, and even aspects of manifold theory. The rush to put the ideas of higher category theory on a firm foundational footing has led to a rich landscape | but also to a glut of definitions, each constructed upon different principles. Until now, there has been very little machinery available to compare the various notions of higher category that have been proposed. The search for a useful comparison of the various notions of higher category has been an elusive and long-standing goal [28].

  • On the Higher Frobenius Allen Yuan
    On the Higher Frobenius by Allen Yuan Submitted to the Department of Mathematics in partial fulfillment of the requirements for the degree of Doctor of Philosophy at the MASSACHUSETTS INSTITUTE OF TECHNOLOGY June 2020 © Massachusetts Institute of Technology 2020. All rights reserved. Author.............................................................. Department of Mathematics April 30, 2020 Certified by . Jacob Lurie Professor of Mathematics Thesis Supervisor Accepted by. Davesh Maulik Chairman, Department Committee on Graduate Theses 2 On the Higher Frobenius by Allen Yuan Submitted to the Department of Mathematics on April 30, 2020, in partial fulfillment of the requirements for the degree of Doctor of Philosophy Abstract Given a homotopy invariant of a space, one can ask how much of the space can be recovered from that invariant. This question was first addressed in work of Quillen and Sullivan on rational homotopy theory in the 1960’s and in work of Dwyer- Hopkins and Mandell on p-adic homotopy theory in the 1990’s. In this thesis, we describe a way to unify these ideas and recover a space in its entirety, rather than up to an approximation. The approach is centered around the study of the higher Frobenius map. First defined by Nikolaus and Scholze, the higher Frobenius map generalizes to E1-ring spectra the classical Frobenius endomorphism for rings in characteristic p. Our main result is that there is an action of the circle group on (a certain subcategory of) p-complete E1-rings whose monodromy is the higher Frobenius. Using this circle action, we give a fully faithful model for a simply connected finite complex X in terms of Frobenius-fixed E1-rings.

This implies a new compatibility between Waldhausen K-theory and Neeman K-theory. Additionally, it provides a new proof of the D´evissage and Localization Theorems of Blumberg{Mandell, new models for the G-theory of schemes, and a proof of the invari- ance of G-theory under derived nil-thickenings.
