A conditional regularity result for p-harmonic flows [PDF]

open access: yes, 2015
We prove an $\varepsilon$-regularity result for a wide class of parabolic systems $$ u_t-\text{div}\big(|\nabla u|^{p-2}\nabla u) = B(u, \nabla u) $$ with the right hand side $B$ growing like $|\nabla u|^p$.

Bounded mean oscillation and the uniqueness of active scalar equations [PDF]

open access: hybridTransactions of the American Mathematical Society, 2014
We consider a number of uniqueness questions for several wide classes of active scalar equations, unifying and generalizing the techniques of several authors. As special cases of our results, we provide a significantly simplified proof to the known uniqueness result for the 2D Euler equations in L 1 ∩

On Global Well-Posedness of the Lagrangian Averaged Euler Equations [PDF]

open access: yes, 2006
We study the global well-posedness of the Lagrangian averaged Euler equations in three dimensions. We show that a necessary and sufficient condition for the global existence is that the bounded mean oscillation of the stream function is integrable in ...

Asymptotic Profile for Diffusion Wave Terms of the Compressible Navier–Stokes–Korteweg System

open access: yesMathematics, 2021
The asymptotic profile for diffusion wave terms of solutions to the compressible Navier–Stokes–Korteweg system is studied on R2. The diffusion wave with time-decay estimate was studied by Hoff and Zumbrun (1995, 1997), Kobayashi and Shibata (2002), and ...

Mean Lipschitz spaces and a generalized Hilbert operator [PDF]

open access: yes, 2017
If $\mu $ is a positive Borel measure on the interval $[0, 1)$ we let $\mathcal H_\mu $ be the Hankel matrix $\mathcal H_\mu =(\mu _{n, k})_{n,k\ge 0}$ with entries $\mu _{n, k}=\mu _{n+k}$, where, for $n\,=\,0, 1, 2, \dots $, $\mu_n$ denotes the moment ...

Equilibrium investment and risk control for an insurer with non-Markovian regime-switching and no-shorting constraints

open access: yesAIMS Mathematics, 2020
In this paper, we study the time-consistent equilibrium investment and risk control policies for an insurer under the mean-variance criterion. The dynamics of liability and assets are given by non-Markovian regime-switching models driven by a Brownian ...

Transpacific transport of benzo[a]pyrene emitted from Asia [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
A global-scale three dimensional atmospheric transport and chemistry model was applied to simulate transpacific transport of Benzo[a]pyrene (BaP) emitted from Asia. The model results were compared with observations at six monitoring sites.

Weighted bounded mean oscillation applied to backward stochastic differential equations [PDF]

open access: greenStochastic Processes and their Applications, 2019
We deduce conditional $L_p$-estimates for the variation of a solution of a BSDE. Both quadratic and sub-quadratic types of BSDEs are considered, and using the theory of weighted bounded mean oscillation we deduce new tail estimates for the solution $(Y,Z)$ on subintervals of $[0,T]$.

On the L_p-solvability of higher order parabolic and elliptic systems with BMO coefficients

open access: yes, 2010
We prove the solvability in Sobolev spaces for both divergence and non-divergence form higher order parabolic and elliptic systems in the whole space, on a half space, and on a bounded domain.

BMO and the John-Nirenberg Inequality on Measure Spaces

open access: yesAnalysis and Geometry in Metric Spaces, 2020
We study the space BMO𝒢 (𝕏) in the general setting of a measure space 𝕏 with a fixed collection 𝒢 of measurable sets of positive and finite measure, consisting of functions of bounded mean oscillation on sets in 𝒢.
