Characteristic classes in deformation quantization [PDF]

, 2014
In deformation quantization one can associate five characteristic functions to (stable) formality morphisms on cochains and chains and to "two-brane" formality morphisms.

Two-sample Tests for Functional Data Using Characteristic Functions

Austrian Journal of Statistics, 2021
In this paper, we consider the two-sample problem for univariate and multivariate functional data. To solve this problem, we use tool of characteristic function and a basis function representation of functional data.

Calculation of the Characteristic Functions of Anharmonic Oscillators [PDF]

, 2010
The energy levels of quantum systems are determined by quantization conditions. For one-dimensional anharmonic oscillators, one can transform the Schrodinger equation into a Riccati form, i.e., in terms of the logarithmic derivative of the wave function.

Evaluating Characteristic Functions of Character Sheaves at Unipotent Elements [PDF]

, 2014
Assume $\mathbf{G}$ is a connected reductive algebraic group defined over an algebraic closure $\mathbb{K} = \overline{\mathbb{F}}_p$ of the finite field of prime order $p>0$.

Planar functions over fields of characteristic two [PDF]

, 2014
Classical planar functions are functions from a finite field to itself and give rise to finite projective planes. They exist however only for fields of odd characteristic.

Exponential Functions for Modelling Hysteresis of Soil-Water Characteristic Curves [PDF]

E3S Web of Conferences, 2020
Soil – water characteristic curve (SWCC) is an important property of unsaturated soils that can be used to estimate various parameters to describe unsaturated soil behavior.

Exceptional planar polynomials [PDF]

, 2014
Planar functions are special functions from a finite field to itself that give rise to finite projective planes and other combinatorial objects. We consider polynomials over a finite field $K$ that induce planar functions on infinitely many extensions of

Constrained characteristic functions, multivariable interpolation, and invariant subspaces

Journal of Inequalities and Applications, 2020
In this paper, we present a functional model theorem for completely non-coisometric n-tuples of operators in the noncommutative variety V f , φ , I ( H ) $\mathcal{V}_{f,\varphi,\mathcal{I}}(\mathcal{H})$ in terms of constrained characteristic functions.
