This proposal describes a broad research program aimed at investigating the consequences of a new perspective on the foundations of algebraic K-theory and on the theory of trace maps to topological Hochschild and cyclic homology (THH and TC). It has long been known that in some sense algebraic K-theory is an invariant of the homotopy theory of the category of modules; this idea can be made precise in terms of a motivic perspective, which views the geometry of rings and schemes as encoded in their categories of modules, making such module categories the central object of study. The PI will develop this perspective to establish conjectures old and new, dramatically advancing our understanding of algebraic K-theory and its deep role in topology, geometry, and arithmetic. The work relies in part on new technology in homotopy theory: the emerging theory of infinity categories and tools arising from the Hill-Hopkins-Ravenel solution of the Kervaire invariant one conjecture. The PI also proposes to develop a program to identify undergraduates interested in mathematics and encourage them to pursue graduate work in the mathematical sciences. The program will expose participants to a novel curriculum emphasizing learning by discovery. The proposed curriculum, incorporating pedagogical techniques from "inquiry-based learning", is based on a software environment supporting an innovative treatment of elementary linear algebra and algebraic topology via guided exploration.The proposed research will advance our current understanding of the bridge between algebra and high-dimensional geometry. Some aspects of the proposed research will have impact on mathematical physics, particularly the study of topological field theories and string theory. The educational program will enhance the development of mathematically trained undergraduates and will leverage the University of Texas' existing strengths in recruiting talented undergraduates from traditionally under-represented groups.

本提案描述了一个广泛的研究计划，旨在研究代数k理论基础和拓扑Hochschild和循环同调（THH和TC）的迹映射理论的新视角的后果。在某种意义上，代数k论是模范畴的同伦论的不变量，这早已为人所知；这个想法可以从动机的角度来看是精确的，它将环和方案的几何形状视为编码在它们的模块类别中，使这些模块类别成为研究的中心对象。PI将发展这一视角来建立新旧猜想，极大地促进我们对代数k理论及其在拓扑，几何和算术中的深刻作用的理解。这项工作部分依赖于同伦理论中的新技术：由Kervaire不变猜想的Hill-Hopkins-Ravenel解产生的无限范畴的新理论和工具。PI还建议制定一项计划，以确定对数学感兴趣的本科生，并鼓励他们从事数学科学的研究生工作。该计划将使参与者接触到强调发现学习的新课程。拟议的课程，结合了“基于探究的学习”的教学技术，是基于一个软件环境，通过引导探索来支持对初等线性代数和代数拓扑的创新处理。提出的研究将推进我们目前对代数和高维几何之间桥梁的理解。本研究的某些方面将对数学物理，特别是拓扑场论和弦论的研究产生影响。该教育项目将加强数学专业本科生的培养，并将利用德克萨斯大学的现有优势，从传统上代表性不足的群体中招募有才华的本科生。
