Perturbation of an α-stable type stochastic process by a pseudo-gradient

Modern Stochastics: Theory and Applications
A Markov process defined by some pseudo-differential operator of an order $1\lt \alpha \lt 2$ as the process generator is considered. Using a pseudo-gradient operator, that is, the operator defined by the symbol $i\lambda |\lambda {|^{\beta -1}}$ with ...

Model independent new physics analysis in $$\Lambda _b\rightarrow \Lambda \mu ^+\mu ^-$$ Λb→Λμ+μ- decay

European Physical Journal C: Particles and Fields, 2018
We study the rare $$\Lambda _b\rightarrow \Lambda \mu ^+\mu ^-$$ Λb→Λμ+μ- decay in the Standard Model and beyond. Beyond the Standard Model we include new vector and axial-vector operators, scalar and pseudo-scalar operators, and tensor operators in the ...

Picone-type identity for pseudo p-Laplacian with variable power

Electronic Journal of Differential Equations, 2012
A Picone type identity is established for homogeneous differential operators involving the pseudo p-Laplacian with variable exponent p=p(x). Using this identity, it is shown that the classical Sturmian theory extends to the associated partial ...

Piecewise weighted pseudo almost periodic solutions of impulsive integro-differential equations via fractional operators

Electronic Journal of Differential Equations, 2015
In this article, we show sufficient conditions for the existence, uniqueness and attractivity of piecewise weighted pseudo almost periodic classical solution of nonlinear impulsive integro-differential equations.

On anisotropic Triebel-Lizorkin type spaces, with applications to the study of pseudo-differential operators

Journal of Function Spaces and Applications, 2008
A construction of Triebel-Lizorkin type spaces associated with flexible decompositions of the frequency space ℝd is considered. The class of admissible frequency decompositions is generated by a one parameter group of (anisotropic) dilations on ℝd and a ...

Properties on measure pseudo almost automorphic functions and applications to fractional differential equations in Banach spaces

Electronic Journal of Differential Equations, 2018
In this article, we establish some new composition theorems on measure pseudo almost automorphic functions via measure theory. The obtained compositions theorems generalize those established under the well-known Lipschitz conditions or the classical ...
