Lecture 19: 5.5: Inner products and Fourier series Def An inner product on a vector space V is a function that for each pair of vectors gives a real number: V 3f;g !hf;gi2R, satisfying: (i) hf;fi 0 with equality if and only if f = 0. (ii) hf;gi= hg;fi. (iii) h f + g;hi= hf;hi+ hg;hi. An inner product space is a vector space with an inner ...

In mathematics, the pointwise product of two functions is another function, obtained by multiplying the images of the two functions at each value in the domain. If f and g are both functions with domain X and codomain Y, and elements of Y can be multiplied (for instance, Y could be some set of numbers), then the pointwise product of f and g is another function from X to Y which maps x in X to f (x)g(x) in Y. Webcompact and has empty boundary. The Riemannian metric induces a pointwise inner product between tangent vectors on M, which, analogously to the above discussion, induces an inner product between 1-forms. More generally, one works with k-forms for k 0. A 0-form, by convention, is a real-valued function on M.
