Advances in Prospect Theory: Cumulative Representation of Uncertainty
 JOURNAL OF RISK AND UNCERTAINTY, 5:297323 (1992)
, 1992
"... We develop a new version of prospect theory that employs cumulative rather than separable decision weights and extends the theory in several respects. This version, called cumulative prospect theory, applies to uncertain as well as to risky prospects with any number of outcomes, and it allows differ ..."

different weighting functions for gains and for losses. Two principles, diminishing sensitivity and loss aversion, are invoked to explain the characteristic curvature of the value function and the weighting functions. A review of the experimental evidence and the results of a new experiment confirm a
Curvature, cones and characteristic numbers
 Math. Proc. Cambridge Philos. Soc
"... Abstract We study Einstein metrics on smooth compact 4manifolds with an edgecone singularity of specified cone angle along an embedded 2manifold. To do so, we first derive modified versions of the GaussBonnet and signature theorems for arbitrary Riemannian 4manifolds with edgecone singularitie ..."

Abstract We study Einstein metrics on smooth compact 4manifolds with an edgecone singularity of specified cone angle along an embedded 2manifold. To do so, we first derive modified versions of the GaussBonnet and signature theorems for arbitrary Riemannian 4manifolds with edgecone singularities, and then show that these yield nontrivial obstructions in the Einstein case. We then use these integral formulae to obtain interesting information regarding gravitational instantons which arise as limits of such edgecone manifolds.
CONNECTIONS, CURVATURE, AND pCURVATURE
"... We begin by describing the classical point of view on connections, their curvature, and pcurvature, in terms of maps of sheaves on a scheme. 1.1. Connections and derivations. Let S be a scheme, and X smooth and finite of 1forms on type over S throughout. We have the rankn vector bundle Ω1 X/S X o ..."

Curvature and characteristic numbers of hyperKähler manifolds
 Duke Math. J
"... Characteristic numbers of compact hyperKähler manifolds are expressed in graphtheoretical form, considering them as a special case of the curvature invariants introduced by L. Rozansky and E. Witten. The appropriate graphs are generated by “wheels, ” and the recently proved Wheeling theorem is used ..."

Characteristics of the curvature effect of uniform jets
, 2005
"... Qin et al. (2004) have derived a formula of count rates based on a model of highly symmetric expanding fireballs, where the Doppler effect is the key factor to be concerned. In this paper, we employ the formula to both the Qin model and the uniform jet model to study how the rising timescale, ∆τθ,r, ..."

ViewInvariant Representation and Recognition of Actions
, 2002
"... Analysis of human perception of motion shows that information for representing the motion is obtained from the dramatic changes in the speed and direction of the trajectory. In this paper, we present a computational representation of human action to capture these dramatic changes using spatiotempor ..."

temporal curvature of 2D trajectory. This representation is compact, viewinvariant, and is capable of explaining an action in terms of meaningful action units called dynamic instants and intervals. A dynamic instant is an instantaneous entity that occurs for only one frame, and represents an important change
WEYL CURVATURE AND THE EULER CHARACTERISTIC IN DIMENSION FOUR
, 2005
"... Abstract. We give lower bounds, in terms of the Euler characteristic, for the L 2norm of the Weyl curvature of closed Riemannian 4manifolds. The same bounds were obtained by Gursky, in the case of positive scalar curvature metrics. 1. ..."

Feature Article The Curvature of Characteristic Curves on Surfaces

Analyzing and interrogating designed surfaces remains an important and widely researched issue in computera ..."
