Perturbations of critical values in nonsmooth critical point theory [PDF]

, 1996
Several theorems about the perturbation of critical values for continuous functionals are proved. Their applications to eigenvalue problems for variational inequalities are given.

On minmax characterization in non-linear eigenvalue problems

Bruno Pini Mathematical Analysis Seminar, 2022
This is a note based on the paper [20] written in collaboration with N. Fusco and Y. Zhang. The main goal is to introduce minimax type variational characterization of non-linear eigenvalues of the p-Laplacian and other results related to shape and ...

Building Bridges between Dependency Theory and Neo-Gramscian Critical Theory: The Agency-Structure Relation as a Starting Point

Contexto Internacional, 2022
Finding common ground between theories that have never or seldom spoken is a necessary first step to bridge-building, particularly concerning their foundational bases.

The ZZ annulus one-point function in non-critical string theory: A string field theory analysis

Journal of High Energy Physics, 2022
We compute the ZZ annulus one-point function of the cosmological constant operator in non-critical string theory, regulating divergences from the boundaries of moduli space using string field theory.

Critical Theory of Non-Fermi Liquid Fixed Point in Multipolar Kondo Problem

Physical Review X, 2020
When the ground state of a localized ion is a non-Kramers doublet, such localized ions may carry multipolar moments. For example, Pr^{3+} ions in a cubic environment would possess quadrupolar and octupolar, but no magnetic dipole, moments.

Deconfined quantum criticality in the two dimensional Kondo lattice model [PDF]

, 2005
We investigate the continuous quantum phase transition from an antiferromagnetic metal to a heavy fermion liquid based on the Kondo lattice model in two dimensions.

Nonlinear response for external field and perturbation in the Vlasov system [PDF]

, 2014
A nonlinear response theory is provided by use of the transient linearization method in the spatially one-dimensional Vlasov systems. The theory inclusively gives responses to external fields and to perturbations for initial stationary states, and is ...

Metamagnetic Quantum Criticality in Sr3Ru2O7 [PDF]

, 2002
We consider the metamagnetic transition in the bilayer ruthenate, ${\rm Sr_3Ru_2O_7}$, and use this to motivate a renormalization group treatment of a zero-temperature quantum-critical end-point.

Deformation techniques in metric critical point theory

Advances in Nonlinear Analysis, 2013
We propose a synthetic and self-contained treatment of the main deformation results of critical point theory, for continuous functionals defined on metric spaces.
