The Homotopy Index and Partial Differential Equations
TL;DR: In this paper, the homotopy index theory and its application to partial differential equations were discussed. But the main properties of the Morse index are the following: isolation invariant sets and isolating blocks, admissibility, and equivalence.
Journal ArticleDOI
On the homotopy index for infinite-dimensional semiflows
TL;DR: In this article, it was shown that the homotopy index is essentially a finite-dimensional concept, and the existence of isolating blocks and index pairs for semislow solutions of partial differential equations with a conditional a-contraction operator was proved.
Journal ArticleDOI
The Effect of Domain Squeezing upon the Dynamics of Reaction-Diffusion Equations
TL;DR: In this paper, it was shown that the reaction-diffusion problem has an upper-semicontinuous family of attractors, and that the family of global attractors (A e)e⩾0 is upper-semidefinite at e = 0.
Journal ArticleDOI
Nonconvergent Bounded Trajectories in Semilinear Heat Equations
Journal ArticleDOI
Ważewski's Principle for retarded functional differential equations
TL;DR: In this paper, the authors present a Razumikhin-type extension of Wazewski's Principle, which is widely applicable to concrete examples, and also an extension of the method to RFDEs with a merely continuous right-hand side.
