Fernholz Joint Professor in Mathematics, Institute for Advanced Study & Princeton University
Bhargav Bhatt received his PhD in mathematics from Princeton University in 2010, spent a decade in Michigan, and is now the Fernholz Joint Professor of Mathematics at the Institute for Advanced Study and Princeton University.
He is interested in algebraic geometry in a broad sense, and especially enjoys arithmetic questions. He has made fundamental contributions to $p$-adic Hodge theory and applied them to longstanding questions in commutative algebra and algebraic topology. His work has been recognized by several awards, including the Infosys Prize, the Nemmers Prize, the Clay Research Award, and the New Horizons Prize.
The $p$-adic world,
General Public Lecture, Wednesday Oct. 21st, 3-4pm, Kittredge Central Hall, Kittredge Multipurpose Room C (KCEN MPR C).
Abstract: What if two numbers were considered close not when their difference is small, but when it is divisible by a large power of a fixed prime $p$? Following this seemingly strange idea leads to the $p$-adic numbers, a concept introduced in the late nineteenth century that has transformed number theory and found applications throughout mathematics. This lecture will explain where the $p$-adic numbers came from, how they differ from the familiar real numbers, and why they are useful.

Recent developments in $p$-adic geometry,
Math Colloquium Lecture, Thursday Oct. 22nd, 11am-12pm, Kittredge Central Hall, Kittredge Multipurpose Room C (KCEN MPR C).
Abstract: Over the past fifteen years, the discovery of perfectoid geometry and related ideas has provided new lenses through which to study $p$-adic spaces at an extraordinarily fine scale. The resulting methods have resolved longstanding questions across algebraic geometry, number theory, homotopy theory, and beyond. In this lecture, I will recount some of this story, emphasizing the applications that motivated the conceptual developments.

DeLong Lecture Reception: Wednesday Oct 21st, 5.30-8pm.
The DeLong Lecture Series is funded by an endowment given by Professor Ira M. DeLong, who came to the University of Colorado in 1888 at the age of 33. Professor DeLong played a fundamental role in the mathematics department as a teacher, researcher and administrator. Professor DeLong was also a prominent citizen of the community of Boulder as well as president of the Mercantile Bank and Trust Company, organizer of the Colorado Education Association, and president of the charter convention that gave Boulder the city manager form of government in 1917. After his death in 1942 it was decided that the bequest he made to the mathematics department would accumulate interest until income became available to fund the DeLong prizes for undergraduates and the DeLong Lectureships to bring outstanding mathematicians to campus each year. The first DeLong Lectures were delivered in the 1962-63 academic year.
