Title: Complexity and Black Hole Geometry

Abstract: The growth of the black hole interior is a mystery. From the field theory point of view, thermal equilibrium is quickly achieved; but from the bulk geometry, one can see that the interior keeps expanding. It is conjectured that this reflects the increase of the state complexity, i.e. the minimal number of simple gates needed to prepare a state starting from some simple reference state. In this talk, I will discuss various aspects of the connection between quantum complexity and geometry. I will show that different kinds of operations are responsible for the growth of different regions of spacetime.
