I. A. Born,K. Schwechheimer,H. Maier,H. F. Ottoterature. The basic concepts necessary to study differential equations - critical points and equilibrium, periodic solutions, invariant sets and invariant manifolds - are discussed first. Stability theory is then developed starting with linearisation methods going back to Lyapunov and Poincaré. In tAlpha-Cells 发表于 2025-3-22 20:50:29

G. Gademann,W. Semmler,T. Lenarztial equations arising in physical problems. Most of the physical phenomena that arise in mathematical physics and engineering fields can be best described by the nonlinear partial differential equations. The problems arise in different areas of applied mathematics, physics, and engineering, includi
