WebNov 24, 2014 · The "all-curl" (divergence-free) vector fields and the "all-divergence" (curl-free) vector fields do "span" the set of vector fields, in the sense that any vector field can be written as a sum of fields of those two types. But they are not "independent" because we do not have a unique way to write a vector field as a sum. WebCurl, similar to divergence is difficult to visualise. It is defined as the circulation of a vector field. Literally how much a vector field ‘spins’. The curl operation, like the gradient, will …

WebIn vector calculus, divergence is a vector operator that operates on a vector field, producing a scalar field giving the quantity of the vector field's source at each point. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around a given point.. As an example, consider air as it is heated or …
