Higher integrability for parabolic systems with Orlicz growth [PDF]
, 2019 We prove higher integrability of the spatial gradient of weak solutions to parabolic systems with $\phi$-growth, where $\varphi=\varphi(t)$ is a general Orlicz function. The parabolic systems need be neither degenerate nor singular.

Higher integrability for nonlinear nonlocal equations with irregular kernel [PDF]
Analysis and Partial Differential Equations on Manifolds, Fractals and Graphs, 2020 We prove a higher regularity result for weak solutions to nonlinear nonlocal equations along the integrability scale of Bessel potential spaces $H^{s,p}$ under a mild continuity assumption on the kernel.

Higher-Dimensional Box Integrals [PDF]
Experimental Mathematics, 2010 Herein, with the aid of substantial symbolic computation, we solve previously open problems in the theory of n-dimensional box integrals Bn (s) := ∊ [0, 1] n . In particular, we resolve an elusive integral called K 5 that previously acted as a “blockade” against closed-form evaluation in n = 5 dimensions.

Bifurcations of Liouville tori of coupled sextic anharmonic oscillators
Journal of Low Frequency Noise, Vibration and Active Control, 2023 In the current paper, the problem of sextic anharmonic oscillators is investigated. There are three integrable cases of this problem. Emphasis is placed on two integrable cases, and a full description of each one is provided.

Manuscripta Mathematica, 1985 Higher integrability results from reverse inequalities for the Hardy- Littlewood maximal function and the Stein-Fefferman sharp function are deduced. A very useful tool in the proofs is the notion of nonincreasing rearrangement of a function, due to Hardy-Littlewood.

Higher integrability for obstacle problem related to the singular porous medium equation
Boundary Value Problems, 2020 In this paper we study the self-improving property of the obstacle problem related to the singular porous medium equation by using the method developed by Gianazza and Schwarzacher (J. Funct. Anal. 277(12):1–57, 2019).

On factorized overlaps: Algebraic Bethe Ansatz, twists, and separation of variables
Nuclear Physics B, 2021 We investigate the exact overlaps between eigenstates of integrable spin chains and a special class of states called “integrable initial/final states”.

Generalized integrability conditions and target space geometry [PDF]
, 2005 In some higher dimensional nonlinear field theories integrable subsectors with infinitely many conservation laws have been identified by imposing additional integrability conditions.

Global higher integrability of weak solutions of porous medium systems [PDF]
Communications on Pure and Applied Analysis, 2019 We establish higher integrability up to the boundary for the gradient of solutions to porous medium type systems, whose model case is given by \begin{equation*} \partial_t u-\Delta(|u|^{m-1}u)=\mathrm{div}\,F\,, \end{equation*} where $m>1$.
