WebThe standard inner product between matrices is hX;Yi= Tr(XTY) = X i X j X ijY ij where X;Y 2Rm n. Notation: Here, Rm nis the space of real m nmatrices. Tr(Z) is the trace of a real square matrix Z, i.e., Tr(Z) = P i Z ii. Note: The matrix inner product is the same as our original inner product between two vectors WebA Hilbert space is an inner product space that is complete with respect to the norm. Completeness is what differentiates the two. Not every metric space can be defined by an inner product, for instance the space of continuous functions on [ 0, 1] with the supremum norm as its metric doesn't come from an inner product. WebIn probability theory, the Feldman–Hájek theorem or Feldman–Hájek dichotomy is a fundamental result in the theory of Gaussian measures.It states that two Gaussian measures and on a locally convex space are either equivalent measures or else mutually singular: there is no possibility of an intermediate situation in which, for example, has a … reagentless organic synthesis
