Weak gravitational lensing with DEIMOS [PDF]
, 2011 We introduce a novel method for weak-lensing measurements, which is based on a mathematically exact deconvolution of the moments of the apparent brightness distribution of galaxies from the telescope's PSF.

On Exceptional Vertex Operator (Super) Algebras [PDF]
, 2014 We consider exceptional vertex operator algebras and vertex operator superalgebras with the property that particular Casimir vectors constructed from the primary vectors of lowest conformal weight are Virasoro descendents of the vacuum.

Hypotheses Tests for Circular Data in Weighted Sampling [PDF]
Journal of Sciences, Islamic Republic of Iran, 2023 This paper is concerned with the problem of statistical hypotheses testing in circular data under weighted sampling. The most powerful test has been obtained when the sampling is subjected to a weight function. Different weight functions are examined for

Poles of maximal order of motivic zeta functions [PDF]
, 2015 We prove a 1999 conjecture of Veys, which says that the opposite of the log canonical threshold is the only possible pole of maximal order of Denef and Loeser's motivic zeta function associated with a germ of a regular function on a smooth variety over a

Some optimal control problems of heat equations with weighted controls
Boundary Value Problems, 2017 In this paper, the time and norm optimal control problems of controlled heat equations with a weight function are considered. For the time optimal problems, we study the following two cases: one is for equations with multi-domain control under null ...

Extrinsic Curvature and the Einstein Constraints [PDF]
, 2002 The Einstein initial-value equations in the extrinsic curvature (Hamiltonian) representation and conformal thin sandwich (Lagrangian) representation are brought into complete conformity by the use of a decomposition of symmetric tensors which involves a ...

On weighted multivariate sign functions
Journal of Multivariate Analysis, 2022 Multivariate sign functions are often used for robust estimation and inference. We propose using data dependent weights in association with such functions. The proposed weighted sign functions retain desirable robustness properties, while significantly improving efficiency in estimation and inference compared to unweighted multivariate sign-based ...

Probability Weighting Functions [PDF]
SSRN Electronic Journal, 2015 Cumulative prospect theory (CPT) has been proposed as an alternative to expected utility theory to explain irregular behavior by economic agents. CPT comprises two key transformations: one of outcome values and the other of objective probabilities. Risk attitudes are derived from the shapes of these transformations as well as their interaction.
