Lower Bounds for Discrepancy
We find the best asymptotic lower bounds for the coefficient of the leading
term of the norm of the two-dimensional (axis-parallel) discrepancy that
can be obtained by K.Roth's orthogonal function method among a large class of
test functions. We use methods of combinatorics, probability, complex and
harmonic analysis.Comment: a slightly different version of the article is accepted to

Predicting Collaboration: Risk, Power, and Dependence in the Gulf of Maine
Collaboration among natural resource organizations and users is touted by researchers as an effective approach to managing common pool resources. To understand how collaboration works, previous studies in organizational theory have identified three variables: power, dependence, and risk. Relationships between actors can be represented by these qualifications of resources or threats and may predict if those relationships are in conflict or asymmetric in power. In this study, the Gulf of Maine transboundary fishery management network relied upon a dyadic influenced survey to quantitatively capture the perception of communication ties between organizations. Four kinds of dependence and three types of risk were captured by respondent responses to be used in predictive and descriptive analysis. The patterns presented a network with low risk and high levels of dependence. Dependence and risk were able to significantly predict whether a relationship was in conflict or whether a relationship had feelings of power, with legitimacy and performance as higher rated indicators. The results suggest that policy makers and network designers should foster legitimacy and shun performance failures when evaluating the relationships among management networks
On the Validity of the 0-1 Test for Chaos
In this paper, we present a theoretical justification of the 0-1 test for
chaos. In particular, we show that with probability one, the test yields 0 for
periodic and quasiperiodic dynamics, and 1 for sufficiently chaotic dynamics
Herman's Theory Revisited
We prove that a -smooth orientation-preserving circle
diffeomorphism with rotation number in Diophantine class ,
, is -smoothly conjugate to a rigid
rotation. We also derive the most precise version of Denjoy's inequality for
such diffeomorphisms.Comment: 10 page
