Social norms evolve with asymmetric sanctions

Nature Human Behaviour, 2018
How social norms evolve over time and what affects their evolution are central questions in the literature about norms. A study suggests that over time, hygiene and violence norms have become stricter, because those who prefer strict norms sanction those who prefer loose norms more than sanctioning in the other direction.

The Dual Space of an Asymmetric Normed Linear Space

Quaestiones Mathematicae, 2003
Given an asymmetric normed linear space ( X , q ), we construct and study its dual space ( X *, q *). In particular, we show that ( x *, q *) is a biBanach semilinear space and prove that ( X , q ) can be identified as a subspace of its bidual by an isometric isomorphism.

Extensions of asymmetric norms to linear spaces

2011
Summary: Let \(M\) be a subset of a (real) linear space that is closed with respect to the sum of vectors and the product by nonnegative scalars. An asymmetric seminorm on \(M\) is a nonnegative and subadditive positively homogeneous function \(q\) defined on \(M\).

Continuous operators on asymmetric normed spaces

Acta Mathematica Hungarica, 2008
For a real linear space, a function \(p:X\to \mathbb R^+\) is called an asymmetric norm on \(X\) if for all \(x,y\in X\) and \(r\in \mathbb R^+\), (i) \(p(x)=p(-x)=0\); (ii) \(p(rx)=rp(x)\); (iii) \(p(x+y)\leq p(x)+p(y)\). For an asymmetric norm \(p\) on \(X\), \(p^{-1}\), defined on \(X\) by \(p^{-1}(x)=p(-x)\) is also an asymmetric norm on \(X\); the

Convergence and left-K-sequential completeness in asymmetrically normed lattices

Acta Mathematica Hungarica, 2012
With \(\mathbb R\), \(\mathbb R^+\), \(\mathbb N\), the sets of real numbers, of positive real numbers and of positive integers, respectively, with \(X\) a real linear space, a function \(p : X\to\mathbb R\) is called an asymmetric norm on \(X\) if, for all \(x,y\in X\) and \(\alpha\in\mathbb R^+\), (a) \(p(x)=p(-x)=0\) iff \(x=0\), (b) \(p(\alpha x ...

Asymmetric labor market institutions in the EMU: Positive and normative implications [PDF]

, 2007
How do asymmetric labor market institutions affect the volatility of innovation and unemployment differentials in a currency union? What are the implications for monetary policy? To answer these questions, this paper sets up a DSGE currency union model with unemployment, hiring frictions and real wage rigidities.

The Banach--Mazur Theorem for Spaces with Asymmetric Norm

Mathematical Notes, 2001
We establish an analog of the Banach—Mazur theorem for real separable linear spaces with asymmetric norm: every such space can be linearly and isometrically embedded in the space of continuous functions f on the interval [0,1] equipped with the asymmetric norm $$||f|$$

Weakly convex sets in asymmetric normed spaces

2017 Constructive Nonsmooth Analysis and Related Topics (dedicated to the memory of V.F. Demyanov) (CNSA), 2017
In this work we present different results for weakly convex sets is spaces with asymmetric seminorm. We present the theorem for the well-posedness of the closest points problem and the Separation Theorem for weakly and strongly convex sets w.r.t. a quasiball.
