We study order theoretic and topological implications for impatience of weakly Paretian, representable orders on infinite utility streams. As a departure from the traditional literature, we do not make any continuity assumptions in proving the existence of impatient points. Impatience is robust in the sense that there are uncountably many impatient points. A general statement about genericity o...

We show that shadowing is a generic property among continuous maps and surjections on large class of locally connected one-dimensional dynamical systems.

ABSTRACT This article presents a survey on null generic impersonal structures conducted with native speaker of Brazilian Portuguese (BP). The objective the was (i) to investigate whether constructions reading need have elements such as fronted adverbials check EPP, hypothesis put forward by Holmberg (2005, 2010a,b); (ii) verify what extent BP-speakers require an overt marker genericity (e.g., c...

This paper analyzes the genericity of bifurcations of one-parameter families of smooth (C1) vector …elds that are embedded in an underlying multidimensional parameter space. Bifurcations with crossing equilibrium loci are called “split bifurcations.”They include, for example, the pitchfork bifurcation and the transcritical bifurcation in one-dimensional systems. In a regular parameter space whe...

We develop several aspects of local and global stability in continuous first order logic. In particular, we study type-definable groups and genericity.
