Fixing Ambiguities in String Theory Using String Field Theory

Explore a 53-minute lecture on fixing ambiguities in string theory using string field theory, presented by Ashoke Sen at ICBS2024. Delve into the groundbreaking work of Balthazar, Rodriguez, and Yin, who discovered remarkable agreements between c=1 matrix model results and D-instanton corrections in two-dimensional string theory. Learn how their analysis left certain constants undetermined in string theory computations, which were initially resolved by comparison with matrix model results. Discover Sen's innovative approach using string field theory to directly fix these constants within string theory calculations. Gain insights into how these findings can be extended to other string theories, advancing our understanding of this complex field of theoretical physics.
