The Background Field Method and the Linearization Problem for Poisson Manifolds [PDF]
, 2004 The background field method (BFM) for the Poisson Sigma Model (PSM) is studied as an example of the application of the BFM technique to open gauge algebras. The relationship with Seiberg-Witten maps arising in non-commutative gauge theories is clarified.

Heliyon, 2020 Soybean is an important cash crop especially for farmers in the north of Ghana. However, cultivation of the commodity is dominated by smallholders equipped with traditional tools, coupled with low or no adoption of improved soybean production ...

Robust biased estimators for Poisson regression model: Simulation and applications
Concurrency and Computation, 2023 The method of maximum likelihood flops when there is linear dependency (multicollinearity) and outlier in the generalized linear models. In this study, we combined the ridge estimator with the transformed M‐estimator (MT) and the conditionally unbiased ...

Generalized Poisson Shock Models
The Annals of Probability, 1981 Suppose that shocks hit a device in accordance with a nonhomogeneous Poisson process with intensity function $\lambda(t)$. The $i^{th}$ shock has a value $X_i$ attached to it. The $X_i$ are assumed to be independent and identically distributed positive random variables, and are also assumed independent of the counting process of shocks.

Generalized Yang Poisson Models on Canonical Phase Space [PDF]
Symmetry, Integrability and Geometry: Methods and ApplicationsWe discuss the generalized Yang Poisson models. We construct generalizations of the Yang Poisson algebra related to $\mathfrak{o}(1,5)$ algebra discussed by Meljanac and Mignemi (2023). The exact realizations of this generalized algebra on canonical phase space are presented and the corresponding differential equations are solved in simple cases ...

The Hitchin Model, Poisson-quasi-Nijenhuis Geometry and Symmetry Reduction
, 2007 We revisit our earlier work on the AKSZ formulation of topological sigma model on generalized complex manifolds, or Hitchin model. We show that the target space geometry geometry implied by the BV master equations is Poisson--quasi--Nijenhuis geometry ...

The Vlasov-Poisson System for Stellar Dynamics in Spaces of Constant Curvature [PDF]
, 2015 We obtain a natural extension of the Vlasov-Poisson system for stellar dynamics to spaces of constant Gaussian curvature $\kappa\ne 0$: the unit sphere $\mathbb S^2$, for $\kappa>0$, and the unit hyperbolic sphere $\mathbb H^2$, for ...

Poisson sigma model on the sphere
, 2009 We evaluate the path integral of the Poisson sigma model on sphere and study the correlators of quantum observables. We argue that for the path integral to be well-defined the corresponding Poisson structure should be unimodular.

Generalized Bregman Divergence and Gradient of Mutual Information for Vector Poisson Channels [PDF]
, 2013 We investigate connections between information-theoretic and estimation-theoretic quantities in vector Poisson channel models. In particular, we generalize the gradient of mutual information with respect to key system parameters from the scalar to the ...

Poisson Model To Generate Isotope Distribution for Biomolecules [PDF]
Journal of Proteome Research, 2017 We introduce a simplified computational algorithm for computing isotope distributions (relative abundances and masses) of biomolecules. The algorithm is based on Poisson approximation to binomial and multinomial distributions. It leads to a small number of arithmetic operations to compute isotope distributions of molecules.
