Abstract:
It is well known from earlier results that certain types of selfadjoint
operators, e.g. operators allowing a representation as operator matrices,
show equipartition of energy. In this paper we examine the question
whether there are more selfadjoint operators showing equipartition of
energy in the Cesaro mean. For this purpose we proof a necessary and
sufficient criterion for equipartition of energy and use this criterion to
show equipartition for a system of partial differential equations with a
coupled boundary condition.
