  2. Inner product space - Wikipedia

    en.wikipedia.org/wiki/Inner_product_space

    Inner product spaces generalize Euclidean vector spaces, in which the inner product is the dot product or scalar product of Cartesian coordinates. Inner product spaces of infinite dimension are widely used in functional analysis. Inner product spaces over the field of complex numbers are sometimes referred to as unitary spaces.

  3. Petersson inner product - Wikipedia

    en.wikipedia.org/wiki/Petersson_inner_product

    The integral is absolutely convergent and the Petersson inner product is a positive definite Hermitian form. For the Hecke operators T n {\displaystyle T_{n}} , and for forms f , g {\displaystyle f,g} of level Γ 0 {\displaystyle \Gamma _{0}} , we have:

  4. Euclidean space - Wikipedia

    en.wikipedia.org/wiki/Euclidean_space

    The inner product of a Euclidean space is often called dot product and denoted x ⋅ y. This is specially the case when a Cartesian coordinate system has been chosen, as, in this case, the inner product of two vectors is the dot product of their coordinate vectors. For this reason, and for historical reasons, the dot notation is more commonly ...

  5. Interior product - Wikipedia

    en.wikipedia.org/wiki/Interior_product

    In mathematics, the interior product (also known as interior derivative, interior multiplication, inner multiplication, inner derivative, insertion operator, or inner derivation) is a degree −1 (anti)derivation on the exterior algebra of differential forms on a smooth manifold.

  6. Outline of algebraic structures - Wikipedia

    en.wikipedia.org/wiki/Outline_of_algebraic...

    The idea is that if the grades of two elements a and b are known, then the grade of ab is known, and so the location of the product ab is determined in the decomposition. Inner product space: an F vector space V with a definite bilinear form V × V → F. Bialgebra: an associative algebra with a compatible coalgebra structure.

  7. Riemannian manifold - Wikipedia

    en.wikipedia.org/wiki/Riemannian_manifold

    The requirement that is a positive-definite inner product then says exactly that this matrix-valued function is a symmetric positive-definite matrix at . In terms of the tensor algebra , the Riemannian metric can be written in terms of the dual basis { d x 1 , … , d x n } {\displaystyle \{dx^{1},\ldots ,dx^{n}\}} of the cotangent bundle as

    With home prices still on the rise in every region of the U.S., 63% of homeowners say they'd rather remodel their homes than move to renovated homes, according to an October survey by Clever Real...

  9. First fundamental form - Wikipedia

    en.wikipedia.org/wiki/First_fundamental_form

    In differential geometry, the first fundamental form is the inner product on the tangent space of a surface in three-dimensional Euclidean space which is induced canonically from the dot product of R 3. It permits the calculation of curvature and metric properties of a surface such as length and area in a manner consistent with the ambient space.
