Homoclinic and Heteroclinic Bifurcations in Vector Fields [chapter]

Ale Jan Homburg, Björn Sandstede
2010 Handbook of Dynamical Systems  
Finally, a few related topics, such as topological moduli, numerical algorithms, variational methods, and extensions to singularly perturbed and infinitedimensional systems, are reviewed briefly. where  ...  Furthermore, v j (µ) is a multiple of the eigenvector of f u (p(µ), µ) associated with ν j (µ) for j = s, u. In addition, there is a constant > 0 so that and analogously for h u (t; µ).  ...  A typical delay differential equation is of the forṁ u(t) = f (u(t), u(t − τ )), u ∈ R n , where τ > 0 is the temporal delay.  ...

Transition to blow-up in a reaction–diffusion model with localized spike solutions

V. ROTTSCHÄFER, J. C. TZOU, M.J. WARD
2017 European journal of applied mathematics  
For certain singularly perturbed two-component reaction–diffusion systems, the bifurcation diagram of steady-state spike solutions is characterized by a saddle-node behaviour in terms of some parameter  ...  More specifically, we use a blend of asymptotic analysis, linear stability theory, and full numerical computations to analyse a wide variety of dynamical instabilities, and ultimately finite-time blow-up  ...  In the analysis, we use a dynamical rescaling approach, based on a near-similarity group transformation, to construct a solution to (1.3) that has finite-time blow-up at x = x 0 .  ...
