*The Great Soviet Encyclopedia*(1979). It might be outdated or ideologically biased.## Vector Field

a region, at each point *P* of which a vector **a( P)** is assigned. Mathematically, a vector field can be defined in a given region

*G*by the vector function

**a(**of the variable point

*P*)*P*of this region. A whole series of physical phenomena and processes (for example, the vectors of the velocities of a moving fluid’s particles at each moment of time form a vector field) lead to the concept of a vector field. Vector-field theory has been extensively developed and has diverse applications in various branches of natural science.
