Quotients and Hopf Images of a Smash Coproduct [PDF]

arXiv, 2015
We describe the Hopf algebra quotients and Hopf images of the smash coproduct of a group algebra by the algebra of functions on a finite group.

First‐order Sobolev spaces, self‐similar energies and energy measures on the Sierpiński carpet

Communications on Pure and Applied Mathematics, EarlyView.
Abstract For any p∈(1,∞)$p \in (1,\infty)$, we construct p$p$‐energies and the corresponding p$p$‐energy measures on the Sierpiński carpet. A salient feature of our Sobolev space is the self‐similarity of energy. An important motivation for the construction of self‐similar energy and energy measures is to determine whether or not the Ahlfors regular ...

On the homotopy groups of the automorphism groups of Cuntz-Krieger algebras [PDF]

arXiv
In this paper, we first present the homotopy groups of the automorphism groups of Cuntz--Krieger algebras in terms of the underlying matrices of the Cuntz--Krieger algebras. We also show that the homotopy groups are complete invariants of the isomorphism class of the Cuntz--Krieger algebras.

Boundary conditions and universal finite‐size scaling for the hierarchical |φ|4$|\varphi |^4$ model in dimensions 4 and higher

Communications on Pure and Applied Mathematics, EarlyView.
Abstract We analyse and clarify the finite‐size scaling of the weakly‐coupled hierarchical n$n$‐component |φ|4$|\varphi |^4$ model for all integers n≥1$n \ge 1$ in all dimensions d≥4$d\ge 4$, for both free and periodic boundary conditions. For d>4$d>4$, we prove that for a volume of size Rd$R^{d}$ with periodic boundary conditions the infinite‐volume ...

Unfolding Electrolyzer Characteristics to Reveal Solar‐to‐Chemical Efficiency Potential: Rapid Analysis Method Bridging Electrochemistry and Photovoltaics

ChemSusChem, Volume 18, Issue 7, April 1, 2025.
A method of unfolding current‐voltage characteristics of electrochemical (EC) cells to assess solar‐to‐chemical efficiencies achievable in combination with any photovoltaic (PV) device under any irradiance, PV‐to‐EC scaling, and power coupling mode.

Electrophoresis of polyelectrolyte‐adsorbed soft particle with hydrophobic inner core

ELECTROPHORESIS, EarlyView.
Abstract This article deals with the electrophoresis of hydrophobic colloids absorbed by a layer of polymers with an exponential distribution of the polymer segments. The functional groups present in the polymer layer further follow the exponential distribution.

Extending Equivalent Circuit Models for State of Charge and Lifetime Estimation

Electrochemical Science Advances, Volume 5, Issue 2, April 2025.
ABSTRACT Equivalent circuit modelling (ECM) of electrochemical impedance spectroscopy (EIS) data is a common technique to describe the state‐dependent response of electrochemical systems such as batteries or fuel cells. To use EIS for predictive assessments of the future behaviour of such a system or its state of health (SOH), a more elaborate digital ...
