H * -algebra
0.1 H *-algebra
An H -algebra is defined as a Hilbert space
equipped with an associative unital algebra structure
and an antilinear involution
which is compatible
with taking the adjoint
of the operators on the Hilbert space for the left and right multiplication of with itself (ref. [1]).
