Courant, Friedrichs and Lewy: partial difference equations of mathematical physics

What changed

Analyzed mesh-limit convergence and characteristic-dependent restrictions for hyperbolic difference problems.

Scientific scope

The record is the exact three-author 1928 German paper, using the later English translation for inspection. Its condition and convergence analysis do not absorb all later stability theory, finite-difference practice or finite-element methods.
