Advanced Linear Algebra 1.1. Hilbert Spaces. In the following, we consider ﬁnite-dimensional vector spaces over C. One can use most of the results also for the case of vector spaces over R simply by observing that R ⊂ C. Some, but far

NettetAn Introduction to Hilbert Space - N. Young 1988-07-21 The notion of a Hilbert space is a central idea in functional analysis and this text demonstrates its applications in numerous branches of pure and applied mathematics. Canadian Mathematical Bulletin - 1994-03 Hilbert Space Operators in Quantum Physics - Jirí Blank 1999-04-23 NettetDenote by B(H) the alge-bra of bounded linear operators on the Hilbert space H. Recall that a Banach algebra A is called a C∗ -algebra if it is isometrically isomorphic with a subalgebra of B(H), closed under taking adjoints. Such an algebra has a natural adjoint operation a → a∗ inherited from B(H).
