摘要
Quantum field theory is a framework for interacting particles and provides a frame to understand our Nature in the fundamental level. Standard Model written in quantum field theory is the theory of all elementary particles and interactions besides the gravity. String/M theory has been studied as a consistent theory of quantum gravity. The progress in string theory led us to the realm of consistent quantum field theories in 5 and 6 dimensional space-time. In addition, a class of consistent 6-dimensional string theory without gravity, so-called little string theories, has emerged. These 6-dim theories have very rich structures with many implications in physics, geometry, black hole physics, and geometric Langlands program. In this seminar, I review some new ideas and discoveries and some further challenges.
