Relative Critical Points [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2013 Relative equilibria of Lagrangian and Hamiltonian systems with symmetry are critical points of appropriate scalar functions parametrized by the Lie algebra (or its dual) of the symmetry group.

CRASHES AS CRITICAL POINTS [PDF]
International Journal of Theoretical and Applied Finance, 2000 We study a rational expectation model of bubbles and crashes. The model has two components: (1) our key assumption is that a crash may be caused by local self-reinforcing imitation between noise traders. If the tendency for noise traders to imitate their nearest neighbors increases up to a certain point called the "critical" point, all noise traders ...

Critical behaviour near critical end points and tricritical points in disordered spin-1 ferromagnets [PDF]
, 2023 Critical end points and tricritical points are multicritical points that separate lines of continuous transitions from lines of first order transitions in the phase diagram of many systems.

Critical fluctuations and complex spinodal points [PDF]
, 2018 The experimental signatures of the QCD critical point rely on the universal singular behavior of the equation of state at the critical point. Therefore, we study singularities of the universal scaling equation of state of the f4 theory, or the Ising ...

Critical points of polynomials [PDF]
, 2021 This paper is devoted to the problem of where the critical points of a polynomial are relative to their zeros. Classical and new developments are surveyed along with illustrative examples.

Critical Points of Strichartz Functional [PDF]
Experimental Mathematics, 2018 We study a pair of infinite dimensional dynamical systems naturally associated with the study of minimizing/maximizing functions for the Strichartz inequalities for the Schrödinger equation. One system is of gradient type and the other one is a Hamiltonian system.

Critical points of orthogonal polynomials [PDF]
, 2017 We study properties of the critical points of orthogonal polynomials with respect to a measure on the unit circle (OPUC). The main result states that, under some conditions, the asymptotic distribution of the critical points of OPUC coincides with the ...

Zero energy critical points of functionals depending on a parameter
, 2023 We investigate zero energy critical points for a class of functionals Φµ defined on a uniformly convex Banach space, and depending on a real parameter µ. More precisely, we show the existence of a sequence (µn) such that Φµn has a pair of critical points

Deconfined Quantum Critical Points [PDF]
Science, 2004 The theory of second-order phase transitions is one of the foundations of modern statistical mechanics and condensed-matter theory. A central concept is the observable order parameter, whose nonzero average value characterizes one or more phases. At large distances and long times, fluctuations of the order parameter(s) are described by a continuum ...

Rigidity of critical points for a nonlocal Ohta-Kawasaki energy [PDF]
, 2016 We investigate the shape of critical points for a free energy consisting of a nonlocal perimeter plus a nonlocal repulsive term. In particular, we prove that a volume-constrained critical point is necessarily a ball if its volume is sufficiently small ...
