Query: A new approach for the strong unique continuation of electromagnetic
  Schroedinger operator with complex-valued coefficient   This paper mainly addresses the strong unique continuation property for the
electromagnetic Schr\"{o}dinger operator with complex-valued coefficients.
Appropriate multipliers with physical backgrounds have been introduced to prove
a priori estimates. Moreover, its application in an exact controllability
problem has been shown, in which case, the boundary value determines the
interior value completely.
