Conjugacy problem in groups with quadratic Dehn function [PDF]

Bulletin of Mathematical Sciences, 2020
We construct a finitely presented group with quadratic Dehn function and undecidable conjugacy problem. This solves Rips’ problem formulated in 1994.

Generalised Weber Functions [PDF]

, 2013
A generalised Weber function is given by $\w_N(z) = \eta(z/N)/\eta(z)$, where $\eta(z)$ is the Dedekind function and $N$ is any integer; the original function corresponds to $N=2$.

On the quadratic Fock functor [PDF]

, 2012
We prove that the quadratic second quantization of an operator p on $L^2(\mathbb{R}^d)\cap L^\infty (\mathbb{R}^d)$ is an orthogonal projection on the quadratic Fock space if and only if p =MI, where MI is a multiplication operator by a characteristic ...

Reconocimiento de las variables visuales y unidades simbólicas significativas de las funciones cuadráticas

Annales de Didactique et de Sciences Cognitives, 2017
In this paper, we explore the qualitative recognition by 144 high school students of the visual variables of the graphical representation of a quadratic function and the significant symbolic units of its algebraic writing.

A Utility Based Approach to Energy Hedging [PDF]

, 2011
A key issue in the estimation of energy hedges is the hedgers' attitude towards risk which is encapsulated in the form of the hedgers' utility function.

Inner product spaces and quadratic functional equations

Advances in Difference Equations, 2021
In this paper, we introduce the functional equations f ( 2 x − y ) + f ( x + 2 y ) = 5 [ f ( x ) + f ( y ) ] , f ( 2 x − y ) + f ( x + 2 y ) = 5 f ( x ) + 4 f ( y ) + f ( − y ) , f ( 2 x − y ) + f ( x + 2 y ) = 5 f ( x ) + f ( 2 y ) + f ( − y ) , f ( 2 x
