elliptic equation

Oscar Buneman

Oscar Buneman (September 28 1913-January 24 1993) made advances in science, engineering, and mathematics. Buneman was a pioneer of computational plasma physics and plasma simulation.

Buneman developed theories and simulations of collisionless dissipation of currents, called the Buneman instability. This is an example of anomalous resistivity or absorption. It is anomalous because the phenonomenon does not depend on collisions. Buneman advanced elliptic equation solver methods and their associated applications (as well as for the fast Fourier transforms). In 1934, Buneman built a differential analyzer at Manchester with Phyllis Lockett, David Copeley, and Douglas Hartree.

Oscar Buneman died near Stanford University.

The computer scientist Peter Buneman is his son.
