Periodic measures and partially hyperbolic homoclinic classes

open access: yes, 2016
In this paper, we give a precise meaning to the following fact, and we prove it: $C^1$-open and densely, all the non-hyperbolic ergodic measures generated by a robust cycle are approximated by periodic measures.

Algebraic structures for transitive closure

open access: yesTheoretical Computer Science, 1977
AbstractClosed semi-rings and the closure of matrices over closed semi-rings are defined and studied. Closed semi-rings are structures weaker than the structures studied by Conway [3] and Aho, Hopcroft and Ullman [1]. Examples of closed semi-rings and closure operations are given, including the case of semi-rings on which the closure of an element is ...

Evaluating Allocations of Opportunities

open access: yesInternational Economic Review, EarlyView.
ABSTRACT This paper provides a robust criterion for comparing lists of probability distributions—interpreted as allocations of opportunities—faced by different social groups. We axiomatically argue in favor of comparing those lists of probability distributions on the basis of a uniform—among groups—valuation of their expected utility.

Context-sensitive transitive closure operators

open access: yesAnnals of Pure and Applied Logic, 1994
This paper continues research initiated by Fagin about the question which (first or second order) logics can capture which complexity classes. The author introduces a new operator, called the context-sensitive transitive closure operator, which is able to express the class PSPACE.

Assessing inconsistencies in the FITradeoff method: a comparison of two preference modeling paradigms

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract Many decision‐making processes are susceptible to errors and inconsistencies introduced by decision‐makers (DMs). The development of decision support systems (DSS) has brought about a way to guide DMs through complex decision scenarios. However, due to the complexity of the process, inconsistencies may still arise.

Local Networks and New Business Formation

open access: yesJournal of Economics &Management Strategy, EarlyView.
ABSTRACT New business formation is a key driver of regional transformation and development. While we know that a region's attractiveness for new businesses depends on its resources, infrastructure, and human capital, we know little about the role of local business networks in promoting or impeding the birth of new firms.
