Clark Edward Barwick (born January 9, 1980) is an American mathematician and professor of pure mathematics at the University of Edinburgh. His research is centered around homotopy theory, algebraic K-theory, higher category theory, and related areas.

Early life and education

Barwick grew up in North Carolina, and in 2001 completed his BS in mathematics at the University of North Carolina at Chapel Hill. [1] [2] Barwick was then a graduate student at the University of Pennsylvania, and received his PhD in mathematics in 2005 under the direction of Tony Pantev.

Career

Barwick held postdoctoral fellowships at the Mathematisches Institut Göttingen (2005–2006) and at the Matematisk Institutt, Universitetet i Oslo (2006–2007). [2] Barwick spent the year 2007–2008 at the Institute for Advanced Study, and from 2008–2010 was a Benjamin Peirce Lecturer at Harvard. In 2010 Barwick became an assistant professor at MIT, and in 2013 he became the Cecil and Ida Green Career Development Assistant Professor of Mathematics. In 2015 Barwick was a Fulbright visiting professor at the University of Glasgow and was promoted to Cecil and Ida Green Career Development Associate Professor of Mathematics at MIT, a position which he held until he became a reader at the University of Edinburgh in 2017. [3] [4] In 2020, Barwick was promoted to a professor at the University of Edinburgh. [5]

Research and notable works

A theme in Barwick's work is the homotopy theory of higher categories. In his early career, he frequently collaborated with Dan Kan; much of their work was concerned with models for the homotopy theory of homotopy theories. In his joint work with Chris Schommer-Pries, Barwick proved a unicity theorem for the homotopy theory of (∞,n)-categories.

Barwick has also made contributions to algebraic K-theory. In particular, Barwick defined higher-categorical generalizations of Waldhausen categories and Waldhausen's S-construction and used these to extend Waldhausen's K-theory to the setting of (∞,1)-categories. Using this new theory, he proved the Theorem of the Heart for Waldhausen K-theory. In joint work with John Rognes, he generalized Quillen's Q-construction to the higher-categorical setting, providing higher-categorical generalizations of Quillen's Theorem B as well as Quillen's dévissage argument in the process. Much of his recent work has concerned equivariant algebraic K-theory and equivariant homotopy theory. Barwick won the 2019 Berwick Prize of the London Mathematical Society for his paper "On the algebraic K-theory of higher categories" where he "proves that Waldhausen's algebraic K-theory is the universal homology theory for ∞-categories, and uses this universality to reprove the major fundamental theorems of the subject in this new context." [6] [7]


In 2019 Barwick with his student Haine introduced the theory of pyknotic objects. Which was published coincidentally and is very closely related to that of condensed sets, with the main differences being set-theoretic in nature: pyknotic theory depends on a choice of Grothendieck universes, whereas condensed mathematics can be developed strictly within ZFC.

Algebraic topology is a branch of mathematics that uses tools from abstract algebra to study topological spaces. The basic goal is to find algebraic invariants that classify topological spaces up to homeomorphism, though usually most classify up to homotopy equivalence.

Algebraic K-theory is a subject area in mathematics with connections to geometry, topology, ring theory, and number theory. Geometric, algebraic, and arithmetic objects are assigned objects called K-groups. These are groups in the sense of abstract algebra. They contain detailed information about the original object but are notoriously difficult to compute; for example, an important outstanding problem is to compute the K-groups of the integers.

In mathematics, a simplicial set is an object composed of simplices in a specific way. Simplicial sets are higher-dimensional generalizations of directed graphs, partially ordered sets and categories. Formally, a simplicial set may be defined as a contravariant functor from the simplex category to the category of sets. Simplicial sets were introduced in 1950 by Samuel Eilenberg and Joseph A. Zilber.

In mathematics, homotopical algebra is a collection of concepts comprising the nonabelian aspects of homological algebra, and possibly the abelian aspects as special cases. The homotopical nomenclature stems from the fact that a common approach to such generalizations is via abstract homotopy theory, as in nonabelian algebraic topology, and in particular the theory of closed model categories.

In mathematics, higher category theory is the part of category theory at a higher order, which means that some equalities are replaced by explicit arrows in order to be able to explicitly study the structure behind those equalities. Higher category theory is often applied in algebraic topology, where one studies algebraic invariants of spaces, such as the fundamental weak ∞-groupoid.

In mathematics, a Waldhausen category is a category C equipped with some additional data, which makes it possible to construct the K-theory spectrum of C using a so-called S-construction. It's named after Friedhelm Waldhausen, who introduced this notion to extend the methods of algebraic K-theory to categories not necessarily of algebraic origin, for example the category of topological spaces.

The Atiyah–Segal completion theorem is a theorem in mathematics about equivariant K-theory in homotopy theory. Let G be a compact Lie group and let X be a G-CW-complex. The theorem then states that the projection map

In algebra, Quillen's Q-construction associates to an exact category an algebraic K-theory. More precisely, given an exact category C, the construction creates a topological space so that is the Grothendieck group of C and, when C is the category of finitely generated projective modules over a ring R, for , is the i-th K-group of R in the classical sense. One puts

In topology, a branch of mathematics, Quillen's Theorem A gives a sufficient condition for the classifying spaces of two categories to be homotopy equivalent. Quillen's Theorem B gives a sufficient condition for a square consisting of classifying spaces of categories to be homotopy Cartesian. The two theorems play central roles in Quillen's Q-construction in algebraic K-theory and are named after Daniel Quillen.

In algebraic K-theory, the K-theory of a categoryC (usually equipped with some kind of additional data) is a sequence of abelian groups Ki(C) associated to it. If C is an abelian category, there is no need for extra data, but in general it only makes sense to speak of K-theory after specifying on C a structure of an exact category, or of a Waldhausen category, or of a dg-category, or possibly some other variants. Thus, there are several constructions of those groups, corresponding to various kinds of structures put on C. Traditionally, the K-theory of C is defined to be the result of a suitable construction, but in some contexts there are more conceptual definitions. For instance, the K-theory is a 'universal additive invariant' of dg-categories and small stable ∞-categories.

In mathematics, nonabelian algebraic topology studies an aspect of algebraic topology that involves higher-dimensional algebras.

In mathematics, homotopy theory is a systematic study of situations in which maps can come with homotopies between them. It originated as a topic in algebraic topology, but nowadays is learned as an independent discipline.
