A new look in the mirror: vibrating strings and curve counting
String theory postulates that the universe is made of quantum particles that are one-dimensional vibrating strings rather than points. It is a way of unifying quantum mechanics and gravity, extending Einstein’s general theory of relativity, which describes gravitational effects as arising from curvature in the fabric of spacetime, to shorter distances and higher energy scales. Mirror symmetry is an important aspect of string theory, intricately related to curve counting, where a complex curve represents the worldsheet of a string propagating through spacetime. With the support of the Marie Skłodowska-Curie Actions programme, the NCMS project is developing a new mathematical approach to mirror symmetry and other curve counting theories.
