Lagrangians and integrability for additive fourth-order difference equations [PDF]

The European Physical Journal Plus, 2020
We use a recently found method to characterise all the invertible fourth-order difference equations linear in the extremal values based on the existence of a discrete Lagrangian. We also give some result on the integrability properties of the obtained family and we put it in relation with known classifications.

Intuitionistic fuzzy stability results of additive functional equation by two different approaches

Journal of Physics: Conference Series, 2021
Abstract In this current work, we examine the Hyers-Ulam(H-U) stability results for a finite variable additive functional equation (Ref.[6]) in Intuitionistic Fuzzy Normed space(IFN-space) is discussed by means of direct and fixed point methods.

Stability of Equilibrium Points of Fractional Difference Equations with Stochastic Perturbations

Advances in Difference Equations, 2008
It is supposed that the fractional difference equation xn+1=(μ+∑j=0kajxn−j)/(λ+∑j=0kbjxn−j), n=0,1,…, has an equilibrium point x^ and is exposed to additive stochastic perturbations type of σ(xn−x^)ξn+1 that are ...

Effect of comorbid mood and anxiety disorders on breast and cervical cancer screening in immune-mediated inflammatory disease

PLoS ONE, 2021
We aimed to examine rates of breast and cervical cancer screening in women with immune-mediated inflammatory diseases (IMID), including inflammatory bowel disease (IBD), multiple sclerosis (MS) and rheumatoid arthritis (RA) versus a matched cohort with ...

Supersymmetric Quantum Mechanics and Solvable Models [PDF]

, 2012
We review solvable models within the framework of supersymmetric quantum mechanics (SUSYQM). In SUSYQM, the shape invariance condition insures solvability of quantum mechanical problems.

Stochastic vortex dynamics in two-dimensional easy-plane ferromagnets: Multiplicative versus additive noise [PDF]

, 1998
We study how thermal fluctuations affect the dynamics of vortices in the two-dimensional classical, ferromagnetic, anisotropic Heisenberg model depending on their additive or multiplicative character. Using a collective coordinate theory, we analytically
