A Morse lemma for degenerate critical points with low differentiability

Abstract and Applied Analysis, 2000
We prove a Morse type lemma for, possibly degenerate, critical points of a C1 function twice strongly differentiable at those points, which allows us to recover, for Finsler metrics, the theorem of Gromoll and Meyer on the existence of infinitely many ...

Sustaining the teaching profession: Innovating the ‘golden thread’ in university‐led teacher education

British Educational Research Journal, EarlyView.
Abstract This paper examines the implications of England's ‘golden thread’ policy framework for teacher education, which describes a state‐mandated, linear model of professional learning from initial teacher training and education through to continuing professional development.

Thermodynamics of DNA with “hump” Morse potential

Eclética Química, 2018
The thermal denaturation of DNA, i.e. the separation of the two strands is a phenomenon caused by the amplitude of the vibrations of the bases, therefore it is necessary to know how such separation is generated in order to implement alternative model of ...

Existence of acyclic matching and Morse complex on transitive digraphs

AKCE International Journal of Graphs and Combinatorics
For any digraph, there exists a transitive closure. The transitive digraph is a discrete geometric object which has a close relationship with simplicial complex.

Structural Aspects of Lithium‐Ion Conduction in the Phosphidotitanate Li8TiP4 and Its Comparison With Li7+5xTa1−xP4 and Li8−xTi1−xTaxP4

Chemistry – A European Journal, EarlyView.
ABSTRACT The chemical system Li/Ti/P has previously been subject to intensive investigation. However, reliable structural data for the reported phases have remained elusive. Motivated by the growing interest in phosphorus‐based lithium‐ion conductors, we have reinvestigated the synthesis, crystal structure, and physical properties of Li8TiP4.

Periodic or homoclinic orbit bifurcated from a heteroclinic loop for high-dimensional systems

Open Mathematics
Consider an autonomous ordinary differential equation in Rn{{\mathbb{R}}}^{n}, which has a heteroclinic loop. Assume that the heteroclinic loop consists of two degenerate heteroclinic orbits γ1{\gamma }_{1}, γ2{\gamma }_{2} and two saddle points with ...
