In this paper we introduce a new concept in dynamical systems: the complex symmetric operator 600" title="Click to view the MathML source">C0-semigroups (groups) acting on Hilbert space. Using techniques of weighted composition operators we study these semigroups on the Fock space 079a03c7f5b2d102f8725b3685a" title="Click to view the MathML source">F2 and show, in particular, that complex symmetric operator 600" title="Click to view the MathML source">C0-semigroups contain the familiar unitary semigroups as a proper subclass.
