Hilbert Space - SymPy 1.11 documentation

In mathematics, an inner product space (or, rarely, a Hausdorff pre-Hilbert space ) is a real vector space or a complex vector space with an operation called an inner product. The inner product of two vectors in the space is a scalar, often denoted with angle brackets such as in . Inner products allow formal definitions of intuitive geometric notions, such as lengths, angles, and orthogonality (zero inner produc… The product of two Hilbert–Schmidt operators has finite trace-class norm; therefore, if A and B are two Hilbert–Schmidt operators, the Hilbert–Schmidt inner product can be defined as The Hilbert–Schmidt operators form a two-sided *-ideal in the Banach algebra of bounded operators on H. They also form a Hilbert … See more In mathematics, a Hilbert–Schmidt operator, named after David Hilbert and Erhard Schmidt, is a bounded operator $${\displaystyle A\colon H\to H}$$ that acts on a Hilbert space $${\displaystyle H}$$ and … See more • Frobenius inner product • Sazonov's theorem • Trace class – compact operator for which a finite trace can be defined See more An important class of examples is provided by Hilbert–Schmidt integral operators.
