scalar field A scalar field is a real-valued function defined on R3 or some subset of R3, though the notion can easily be extended to other dimensions. A field will usually be assumed to have continuous derivatives (see continuous function). Scalar fields are common in physical applied mathematics (examples include temperature, pressure, density, gravitational potential) but may also be studied in their own right in multivariable calculus. Compare vector field.
