21Laplace-Gleichung — Lösung der Laplace Gleichung auf einem Kreisring mit den Dirichlet Randwerten u(r=2)=0 und u(r=4)=4sin(5*θ) Die Laplace Gleichung (nach Pierre Simon Laplace) ist die elliptische partielle Differentialgleichung zweiter Ordnung ΔΦ = 0 für eine… …
22Laplace transform — Math. a map of a function, as a signal, defined esp. for positive real values, as time greater than zero, into another domain where the function is represented as a sum of exponentials. Cf. Fourier transform. [1940 45; after P. S. LAPLACE] * * *… …
