Scalar (mathematics)
A scalar is an element of a field which is used to define a ''vector space''.
In linear algebra, real numbers or generally elements of a field are called scalars and relate to vectors in an associated vector space through the operation of sca ...
, an element of a field, which is used to define a vector space, usually the field of real numbers

Scalar (physics), a physical quantity that can be described by a single element of a number field such as a real number
**
Lorentz scalar
In a relativistic theory of physics, a Lorentz scalar is an expression, formed from items of the theory, which evaluates to a scalar, invariant under any Lorentz transformation. A Lorentz scalar may be generated from e.g., the scalar product of ...
, a quantity in the theory of relativity which is invariant under a Lorentz transformation
**
Pseudoscalar
In linear algebra, a pseudoscalar is a quantity that behaves like a scalar, except that it changes sign under a parity inversion while a true scalar does not.
Any scalar product between a pseudovector and an ordinary vector is a pseudoscalar. T ...
, a quantity that behaves like a scalar, except that it changes sign under a parity inversion

Inner product space
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 ...
