Lyapunov stability is named after Aleksandr Mikhailovich Lyapunov, a Russian mathematician who defended the thesis The General Problem of Stability of Motion at Kharkov University in 1892. A. M. Lyapunov was a pioneer in successful endeavors to develop a global approach to the analysis of the stability of … See more Various types of stability may be discussed for the solutions of differential equations or difference equations describing dynamical systems. The most important type is that concerning the stability of solutions near to a point of … See more Consider an autonomous nonlinear dynamical system $${\displaystyle {\dot {x}}=f(x(t)),\;\;\;\;x(0)=x_{0}}$$, where $${\displaystyle x(t)\in {\mathcal {D}}\subseteq \mathbb {R} ^{n}}$$ denotes the See more Assume that f is a function of time only. • Having $${\displaystyle {\dot {f}}(t)\to 0}$$ does not imply that $${\displaystyle f(t)}$$ has a limit at See more • Bhatia, Nam Parshad; Szegő, Giorgio P.
