Joachim Weidmann Book order

Focusing on the theory of linear operators in Hilbert spaces, this book serves as an accessible introduction for students and professionals alike. It incorporates simplified proofs, additional exercises, and new results, enhancing the original German edition. The text assumes a basic understanding of complex analysis and ordinary differential equations, making it suitable for advanced students. Additionally, it compiles essential results from Lebesgue integration theory, providing a comprehensive resource for both learning and research in mathematical physics.

They give a complete spectral theory for ordinary differential expressions of arbitrary order n operating on -valued functions existence and construction of self-adjoint realizations via boundary conditions, determination and study of general properties of the resolvent, spectral representation and spectral resolution.
