  2. Steven Strogatz - Wikipedia

    en.wikipedia.org/wiki/Steven_Strogatz

    Strogatz's writing for the general public includes four books and frequent newspaper articles. His book Sync [23] was chosen as a Best Book of 2003 by Discover Magazine. [24] His 2009 book The Calculus of Friendship [25] was called "a genuine tearjerker" [26] and "part biography, part autobiography and part off-the-beaten-path guide to calculus."

  3. Dynamical systems theory - Wikipedia

    en.wikipedia.org/wiki/Dynamical_systems_theory

    Dynamical systems theory and chaos theory deal with the long-term qualitative behavior of dynamical systems.Here, the focus is not on finding precise solutions to the equations defining the dynamical system (which is often hopeless), but rather to answer questions like "Will the system settle down to a steady state in the long term, and if so, what are the possible steady states?", or "Does ...

  4. Watts–Strogatz model - Wikipedia

    en.wikipedia.org/wiki/Watts–Strogatz_model

    The Watts–Strogatz model is a random graph generation model that produces graphs with small-world properties, including short average path lengths and high clustering. It was proposed by Duncan J. Watts and Steven Strogatz in their article published in 1998 in the Nature scientific journal. [ 1 ]

  5. Hopf bifurcation - Wikipedia

    en.wikipedia.org/wiki/Hopf_bifurcation

    Complex eigenvalues of an arbitrary map (dots). In case of the Hopf bifurcation, two complex conjugate eigenvalues cross the imaginary axis. In the mathematical theory of bifurcations, a Hopf bifurcation is a critical point where, as a parameter changes, a system's stability switches and a periodic solution arises. [1]

  6. Method of dominant balance - Wikipedia

    en.wikipedia.org/wiki/Method_of_dominant_balance

    The method may be iterated to generate additional terms of an asymptotic expansion to provide a more accurate solution. [11] Iterative methods such as the Newton-Raphson method may generate a more accurate solution. [4] A perturbation series, using the approximate solution as the first term, may also generate a more accurate solution. [5]

  7. Duncan J. Watts - Wikipedia

    He is also author of two books. His first, Six Degrees: The Science of a Connected Age [ 4 ] is based on the six degrees research in his 1998 paper with Steven Strogatz , in which the two presented a mathematical theory of the small world phenomenon . [ 17 ]

  9. Limit cycle - Wikipedia

    en.wikipedia.org/wiki/Limit_cycle

    Stable limit cycle (shown in bold) and two other trajectories spiraling into it Stable limit cycle (shown in bold) for the Van der Pol oscillator. In mathematics, in the study of dynamical systems with two-dimensional phase space, a limit cycle is a closed trajectory in phase space having the property that at least one other trajectory spirals into it either as time approaches infinity or as ...
