Solenoidal vector field.

A vector field F is said to be conservative if it has the property that the line integral of F around any closed curve C is zero: ∮ C F · d r = 0. Equivalently F is conservative if the line integral of F along a curve only depends on the endpoints of the curve, not on the path taken by the curve, ∫ C1 F · d r = ∫ C2 F · d r.Vector Calculus:- Vector Differentiation: Scalar and vector fields.

The vector fields in these bases are solenoidal; i.e., divergence-free. Because they are divergence-free, they are expressible in terms of curls. Furthermore, the divergence-free property implies that they are functions of only two scalar fields. For each geometry, we write down two classes of vector fields, each dependent on a scalar function.A necessary step in the analysis of both the control problems and the related boundary value problems is the characterization of traces of solenoidal vector fields.

It is represented by the symbol (called nabla, for a Phoenician harp in greek). As a result, the gradient is a directional derivative.

A vector field F in R3 is called irrotational if curlF = 0. This means, in the case of a fluid flow, that the flow is free from rotational motion, i.e, no whirlpool. Fact: If f be a C2 scalar field in R3. Then ∇f is an irrotational vector field, i.e., curl (∇f )=0.
