Estimates for critical groups of solutions to quasilinear elliptic systems

open access: yesElectronic Journal of Differential Equations, 2003
In this work we study a class of functionals, defined on Banach spaces, associated with quasilinear elliptic systems. Firstly, we prove some regularity results about the critical points of such functionals and then we estimate the critical groups in each

Critical theories of phase transition between symmetry protected topological states and their relation to the gapless boundary theories

open access: yes, 2013
Symmetry protected topological states (SPTs) have the same symmetry and the phase transition between them are beyond Landau's symmetry breaking formalism.

Properties of critical groups

open access: yesJournal of Algebra, 1980
Knowledge of properties and of the structure of so-called f-cr i t ical groups for a given class f of groups can often help to get detailed information for the structure of those groups, which belong to f . I f f is a class of groups, we say that a group G is f-cri t ical , if G ¢ f , but H ~ f for all proper subgroups H o f G.

Post-critically finite self-similar groups

open access: yes, 2003
We describe in terms of automata theory the automatic actions with post-critically finite limit space. We prove that these actions are precisely the actions by bounded automata and that any self-similar action by bounded automata is contracting.

On the critical pair theory in abelian groups : Beyond Chowla's Theorem

open access: yes, 2007
We obtain critical pair theorems for subsets S and T of an abelian group such that |S+T| < |S|+|T|+1. We generalize some results of Chowla, Vosper, Kemperman and a more recent result due to Rodseth and one of the authors.Comment: Submitted to ...

Critical swimming speed in groups of Atlantic salmon Salmo salar

open access: yesAquaculture Environment Interactions, 2016
Critical swimming speed (Ucrit) has traditionally been measured in relatively small swimming tunnels with 1 fish alone. However, both increased flume lengths and swimming in groups are known to improve performance.

Cyclic Critical Groups of Graphs

open access: yes, 2016
In this note, we describe a construction that leads to families of graphs whose critical groups are cyclic. For some of these families we are able to give a formula for the number of spanning trees of the graph, which then determines the group ...

Critical percolation on certain non-unimodular graphs [PDF]

open access: yes, 2005
An important conjecture in percolation theory is that almost surely no infinite cluster exists in critical percolation on any transitive graph for which the critical probability is less than 1. Earlier work has established this for the amenable cases Z^2

Resonant (p,q)-equations with Robin boundary condition

open access: yesElectronic Journal of Differential Equations, 2018
We consider a nonlinear nonhomogeneous Robin problem that has the sum of a p-Laplacian and a q-Laplacian (a (p,q)-equation). The reaction term is a Caratheodory function which is resonant at $\pm\infty$ with respect to any nonprincipal variational ...
