β¦ Synopsis
Controllability problems for N strings or beams controlled from a common endpoint are studied. We give necessary and su cient conditions for simultaneous spectral and approximate controllability and describe the space of simultaneously reachable states as a function of the position of the endpoint. For each type of controllability result the sharp controllability time is obtained. The proofs are based on new results in nonharmonic Fourier series which describe Riesz bases of exponential divided di erences.

## Abstract This paper considers transmission problem for the system of electromagnetoβelasticity having piecewise constant coefficients in a bounded domain. The result on exact boundary controllability is obtained provided the interfaces, where the coefficients have a jump discontinuity, are all s
