Topological Degree Approach to Bifurcation Problems

Topological bifurcation thought is likely one of the such a lot crucial issues in arithmetic. This booklet comprises unique bifurcation effects for the lifestyles of oscillations and chaotic behaviour of differential equations and discrete dynamical structures less than edition of concerned parameters. utilizing topological measure thought and a perturbation procedure in dynamical structures, a vast number of nonlinear difficulties are studied, together with: non-smooth mechanical structures with dry frictions; systems with relay hysteresis; differential equations on countless lattices of Frenkel-Kontorova and discretized Klein-Gordon forms; blue sky catastrophes for reversible dynamical platforms; buckling of beams; and discontinuous wave equations.

Low-dimensional topology,

This quantity contains the complaints of a convention held on the college university of North Wales (Bangor) in July of 1979. It assembles examine papers which mirror different currents in low-dimensional topology. The topology of 3-manifolds, hyperbolic geometry and knot concept become significant issues.

Infinite-dimensional dynamical systems : an introduction to dissipative parabolic PDEs and the theory of global attractors

"This booklet develops the speculation of worldwide attractors for a category of parabolic PDEs that incorporates reaction-diffusion equations and the Navier-Stokes equations, examples which are taken care of intimately. A long bankruptcy on Sobolev areas presents the framework that enables a rigorous remedy of life and strong point of options for either linear time-independent difficulties (Poisson's equation) and the nonlinear evolution equations that generate the infinite-dimensional dynamical structures of the identify.
