Research Summary
研究概要
My research interests are in the deep understanding of the structure of spacetime that requires quantum gravity theory, such as black holes.
In particular, I am interested in a gravity theory covariant to the duality of string theory.
The “winding” effect unique to strings is expected to give a new geometric picture of spacetime.
My research goal is to explain the internal structure of black holes and the spacetime structure of the early universe by additional degrees of freedom derived from string windings.
