Renormalization group and critical localization

Physical Review B, 1977
The renormalization-group (RG) method is applied to the problem of formation of a localized state of a particle moving in a given potential. It is shown that RG transformation on the particle's Green's function can be performed exactly. The fixed-point equations yield information on the critical binding strength, while the transformation equations near

Critical degenerate inequalities¶on the Heisenberg group

manuscripta mathematica, 2001
The author obtains necessary conditions for the existence of (signed) weak solutions for the singular inequalities on the Heisenberg group: \({{-| \xi| ^2_{H}}\over {\psi}} \Delta_H (au) \geq | u| ^q,\) on \(I\!\! H^n \setminus\{0\}\) \; \(u_t -{{| \xi| ^2_{H}}\over {\psi}} \Delta_H (au) \geq | u| ^q,\) and \(u_{tt} -{{| \xi| ^2_{H}}\over {\psi ...

Morse Theory and Critical Groups

2019
Let H be a Hilbert space with inner product \((\cdot ,\cdot )_H\) and let \(\varphi \in C^2(H)\). By \(\varphi '(\cdot )\) we denote the Frechet derivative of \(\varphi \) and by \(\nabla \varphi (\cdot )\) its gradient, that is, \(\nabla \varphi (u)\in H\) for every \(u\in H\) and.

Critical Service Learning and Group

2018
Critical service learning (CSL) emphasizes that youth become empowered to see themselves as partners with others to bring about change in their environments (Muscott, 2000). The nature of CSL evokes youth voice and choice in the application of cognitive, social, and emotional skills to everyday situations.
