D-holomorphic Functions
The function f is called D-holomorphic when
- 0 = (∂/∂x − j ∂/∂y) ( u + j v)
- = ux − j2 vy + j (vx − uy ).
The consequent partial differential equations are called "Scheffers' conditions" by Isaak Yaglom who credits Georg Scheffers' work of 1893. See Duren's text for the use of similar differential operators to establish the relation of harmonic function theory to analytic functions on the ordinary complex plane C .It is apparent that the components u and v of a D-holomorphic function f satisfy the wave equation, associated with D'Alembert, whereas components of C-holomorphic functions satisfy Laplace's equation.

Famous quotes containing the word functions:
“If photography is allowed to stand in for art in some of its functions it will soon supplant or corrupt it completely thanks to the natural support it will find in the stupidity of the multitude. It must return to its real task, which is to be the servant of the sciences and the arts, but the very humble servant, like printing and shorthand which have neither created nor supplanted literature.”
—Charles Baudelaire (1821–1867)
