In mathematics, a heteroclinic cycle is an invariant set in the phase space of a dynamical system. It is a topological circle of equilibrium points and connecting heteroclinic orbits. If a heteroclinic cycle is asymptotically stable, approaching trajectories spend longer and longer periods of time in a neighbourhood of successive equilibria. In generic dynamical systems heteroclinic connections are of high co-dimension, that is, they will not persist if parameters are varied. (Wikipedia).

Homogeneous vs Heterogeneous Catalysts - Basic Introduction
This video provides a basic introduction into homogeneous and heterogeneous catalysts. A Homogeneous catalyst exists in the same phase as the reactants and products. A heterogeneous catalyst exists in a different phase as the reactants and products. New Chemistry Video Playlist: https

Heterocycles Part 1: Furan, Thiophene, and Pyrrole
We've mentioned heterocycles before. They are cyclic molecules where one or more atoms in the ring are not carbon. Typically these involve oxygen, nitrogen, and sulfur. But there are so many different heterocycles. Different sizes, some aromatic and some not, and many of them are important

Homotopic, Enantiotopic, Diastereotopic, and Heterotopic Protons
In doing NMR spectroscopy, we must be able to predict chemical shifts for a variety of protons. When comparing specific pairs of protons, we can assign them a few different relationships, those being homotopic, enantiotopic, diasteretopic, and heterotopic. Let's see what these words mean a

A Level Chemistry Revision "Heterogeneous and Homogeneous Catalysts"
In this video, we look at heterogeneous and homogeneous catalysts. First we explore heterogeneous catalysts, using the Haber process as an example. We look at how heterogeneous catalysts work in terms of adsorption and desorption. We then look at homogeneous catalysts using the reactions o

Theodore Vo: Canards, Cardiac Cycles, and Chimeras
Abstract: Canards are solutions of singularly perturbed ODEs that organise the dynamics in phase and parameter space. In this talk, we explore two aspects of canard theory: their applications in the life sciences and their ability to generate new phenomena. More specifically, we will use

Particle trajectories integrated through the double gyre illustrate heteroclinic tangle
This movie illustrates the chaotic motion of particles in the double gyre vector field. Particle trajectories that start near the backward-time Lagrangian coherent structure (LCS) ridge are integrated backward in time, where they begin to adhere to the positive-time LCS ridge. The time-d

Abstract: In this paper we prove an analogue of the Brakke's $\epsilon$-regularity theorem for the parabolic Allen--Cahn equation. In particular, we show uniform $C^{2,\alpha}$ regularity for the transition layers converging to smooth mean curvature flows as $\epsilon\rightarrow 0$. A corr

The study of combinatorial dynamical systems goes back to the seminal 1998 papers by Robin Forman. The main motivation to study combinatorial dynamics comes from data science. Combinatorial dynamics also provides very concise models of dynamical phenomena. Moreover, some topological invari

Abstract: We prove an optimal relative integral convergence rate for two expanding gradient Ricci solitons coming out of the same cone. As a consequence, we obtain a unique continuation result at infinity and we prove that a relative entropy for two such self-similar solutions to the Ricci
