The Boundary Control method can be used to solve several coefficient determi nation for wave equations. Furthermore, similar inverse problems for many other partial differential equations can be reduced to these problems. This is the case for inverse problems for heat and non-stationary Schrödinger equations, as well as for several fractional equations. Inverse problems for linear elliptic equations on a wave guide, and some non-linear elliptic equations are also covered by this theory. These lectures will give an introductory exposition of the method.
