Hermitian Symmetry (contd.) This symmetry matches the symmetry of the functions which comprise the Fourier basis: ej2pst =ej2ps( t): Created Date: In mathematical analysis, a Hermitian function is a complex function with the property that its complex conjugate is equal to the original function with the variable changed in sign: (where the indicates the complex conjugate) for all in the domain of . In physics, this property is referred to as PT symmetry. This definition extends also to functions of two or more variables, e.g., in the case that is a functi… covid vaccine that kills the virus
