It is proved that if a group of unitary operators and a local semigroup of isometries satisfy the Weyl commutation relations then they can be extended to groups of unitary operators which also satisfy the commutation relations. As an application a result about the extension of a class of locally def
An invariant Hermitian operator is constructed for the Heisenberg spin system in a time-dependent magnetic field. Using it we obtain the general solution of the Schrodinger equation for this system. By virtue of the general solution, the geometric phase of Pancharatnam type is worked out.
