WebFeb 12, 2024 · In this paper we study the Bergman kernels of a singular Hermitian line bundle over a Riemann surface under the assumption that the curvature has singularities of Poincaré type at a finite set. WebHermitian operators (i.e., self-adjoint operators): N* = N Skew-Hermitian operators: N* = − N positive operators: N = MM* for some M (so N is self-adjoint). A normal matrix is the matrix expression of a normal operator on the Hilbert space Cn . Properties [ edit] Normal operators are characterized by the spectral theorem. bowie county cad map
