A class of indecomposable representations of Uq(s`n) is considered for q an even root of unity (qh = −1 ) exhibiting a similar structure as (height h ) indecomposable lowest weight Kac-Moody modules associated with a chiral conformal field theory. In particular, Uq(s`n) counterparts of the Bernard-Felder BRS operators are constructed for n = 2, 3 . For n = 2 a pair of dual d2(h) = h dimensional...

This paper is intended to provide conditions for the stability of the strong uniqueness of the optimal solution of a given linear semi-in…nite optimization (LSIO) problem, in the sense of the maintaining of the strong uniqueness property under su¢ ciently small perturbations of all the data. We consider LSIO problems such that the family of gradients of all the constraints is unbounded, extendi...

A minimal representation of a simple non-compact Lie group is obtained by “quantizing” the minimal nilpotent coadjoint orbit of its Lie algebra. It provides context for Roger Howe’s notion of a reductive dual pair encountered recently in the description of global gauge symmetry of a (4-dimensional) conformal observable algebra. We give a pedagogical introduction to these notions and point out t...

Conventional wisdom, and a growing body of behavioral research, suggests that the nonverbal image of a candidate influences voter decision making. We presented subjects with images of political candidates and asked them to make four trait judgments based solely on viewing the photographs. Subjects were asked which of the two faces exhibited more competence, attractiveness, deceitfulness, and th...

Optimality principles of biological movement are conceptually appealing and straightforward to formulate. Testing them empirically, however, requires the solution to stochastic optimal control and estimation problems for reasonably realistic models of the motor task and the sensorimotor periphery. Recent studies have highlighted the importance of incorporating biologically plausible noise into ...

This introduction to the R package rrcov is a (slightly) modified version of Todorov and Filzmoser (2009), published in the Journal of Statistical Software. Taking advantage of the S4 class system of the programming environment R, which facilitates the creation and maintenance of reusable and modular components, an object oriented framework for robust multivariate analysis was developed. The fr...

Abstract The European travel narratives that follow the discovery of New World have already been extensively studied, from historical, anthropological and literary perspectives. However, we would like to reread them perspective tension between a “marvellous possession” (Greenblatt 1991) more profound failure. early travelogues show complex discursive architecture with textual subject facing an ...
