A structurally localized ensemble Kalman filtering approach
Quarterly Journal of the Royal Meteorological Society, EarlyView.We derive an inherently localized ensemble Kalman filtering (EnKF) approach, avoiding the need for any auxiliary localization technique. The idea is to first use the variational Bayesian optimization to approximate the (continuous) state analysis probability density function (pdf) by a product of independent marginal pdfs corresponding to small ...

Deformed Schur indices of BCD-type for $$\mathcal{N}=4$$ super Yang-Mills and symmetric functions
Journal of High Energy PhysicsWe investigate the deformed Schur index in four dimensional $$\mathcal{N}=4$$ super Yang-Mills theories with SO and Sp gauge groups, generalizing Hatsuda’s recent calculations.

On Higher Frobenius-Schur Indicators
, 2005 We study the higher Frobenius-Schur indicators of modules over semisimple Hopf algebras, and relate them to other invariants as the exponent, the order, and the index. We prove various divisibility and integrality results for these invariants.

Schur Index Two and Bilinear Forms
Journal of Algebra, 1993 Let \(G\) be a finite group, \(F\) some real field and \(\chi\) some complex irreducible character of \(G\) with values in \(F\) such that \(m_ F(\chi) \neq 1\) (where \(m_ F(\chi)\) denotes the Schur index of \(\chi\) with respect to \(F\)). Let \(M\) be an \(FG\)-module affording the character \(m_ F(\chi)\chi\) and \(f\) be some \(G\)-invariant ...

Superconformal index, BPS monodromy and chiral algebras
Journal of High Energy Physics, 2017 We show that specializations of the 4d N=2 $$ \mathcal{N}=2 $$ superconformal index labeled by an integer N is given by Tr ℳ N where ℳ is the Kontsevich-Soibelman monodromy operator for BPS states on the Coulomb branch.

A majorization method for localizing graph topological indices
, 2011 This paper presents a unified approach for localizing some relevant graph topological indices via majorization techniques. Through this method, old and new bounds are derived and numerical examples are provided, showing how former results in the ...

International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT This paper is concerned with the platooning control problem of connected automated vehicles (CAVs) under non‐uniform stochastic vehicle‐to‐vehicle (V2V) communication delays. Most existing relevant studies assume uniform or deterministic or slowly varying delays, or design platoon controllers based on worst‐case delay bounds, resulting in ...

The Schur index of the 𝑝-regular characters of the Borel subgroup [PDF]
Proceedings of the American Mathematical Society, 1979 Let B be the group of F q {{\mathbf {F}}_q} -rational points of the Borel subgroup of a connected reductive group defined over the finite field F q {{\mathbf {F}}_q}

Measured‐State Conditioned Recursive Feasibility for Stochastic Model Predictive Control
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT In this paper, we address the problem of designing stochastic model predictive control (SMPC) schemes for linear systems affected by unbounded disturbances. The contribution of the paper is rooted in a measured‐state initialization strategy. First, due to the nonzero probability of violating chance‐constraints in the case of unbounded noise ...

Schur line defect correlators and giant graviton expansion
Journal of High Energy PhysicsWe consider Schur line defect correlators in four dimensional N $$ \mathcal{N} $$ = 4 U(N) SYM and their giant graviton expansion encoding finite N corrections to the large N limit.
