## Complexity Theory

**Date:**
23 - 26 July 2018

**Location: ** Mathematical Institute, University of Oxford

**Event type:**
CMI Workshop

**Organisers: ** Eric Allender (Rutgers), Ben Green (Oxford), Rahul Santhanam (Oxford)

This workshop will focus on a unifying theme in recent research on complexity theory, informally termed “meta-complexity.” Meta-complexity refers to the computational complexity of problems whose instances themselves encode algorithms or computations. Some of the fundamental questions in theoretical computer science are questions about meta-complexity, including: Is the Satisfiability Problem solvable in less than exponential time? Do pseudo-random generators exist? Is efficient learning of concepts feasible? Are complexity lower bounds provable in standard proof systems?

These questions connect complexity theory to a wide range of other areas, including algorithms, learning, cryptography, and logic. This workshop will build on these connections by stimulating cross-disciplinary conversations between researchers and students working in these areas, with the aim of achieving a deeper and more integrated mathematical understanding of computation.
