Paraproducts for bilinear multipliers associated with convex sets
Mathematische Annalen, 2022 AbstractWe prove bounds in the local $$ L^2 $$ L 2 range for exotic paraproducts motivated by bilinear multipliers associated with convex sets. One result assumes an exponential boundary curve. Another one assumes a higher order lacunarity condition.

A bilinear Rubio de Francia inequality for arbitrary squares [PDF]
, 2016 We prove the boundedness of a smooth bilinear Rubio de Francia operator associated with an arbitrary collection of squares (with sides parallel to the axes) in the frequency plane\[\left(f, g \right)\mapsto \left( \sum\_{\omega \in \Omega}\left| \int\_ ...

A mixed method for Dirichlet problems with radial basis functions
, 2013 We present a simple discretization by radial basis functions for the Poisson equation with Dirichlet boundary condition. A Lagrangian multiplier using piecewise polynomials is used to accommodate the boundary condition.

Finite Element Modelling of Rocking and Hybrid Precast Walls under Seismic Loading
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT In recent years, self‐centring systems have received considerable research interest in the seismic design of precast concrete structures for their ability to limit damage and satisfy resilience requirements. Rocking and hybrid structural walls, characterised by the formation of a single gap at the wall–foundation interface, mitigate damage by ...

Some endpoint estimates for bilinear Coifman-Meyer multipliers
Journal of Mathematical Analysis and Applications, 2021 In this paper we establish mapping properties of bilinear Coifman-Meyer multipliers acting on the product spaces $H^1(\mathbb{R}^n)\times\mathrm{bmo}(\mathbb{R}^n)$ and $L^p(\mathbb{R}^n)\times\mathrm{bmo}(\mathbb{R}^n)$, with ...

International Journal for Numerical Methods in Fluids, EarlyView.We introduce an efficient open‐source numerical framework for the automated search for the placements of injection and production wells in hot fracture‐controlled reservoirs that sustainably optimize geothermal energy production. We model the reservoirs as discrete fracture networks in 3D. The fluid flow and heat transport in the reservoirs are modeled

Elliptic solutions to difference non-linear equations and related many-body problems
, 1997 We study algebro-geometric (finite-gap) and elliptic solutions of fully discretized KP or 2D Toda equations. In bilinear form they are Hirota's difference equation for $\tau$-functions.

International Journal of Climatology, EarlyView.Future runoff in China shows strong regional and seasonal disparities, with the Southeast basin seeing the largest increase in annual runoff. Wetter summers and drier winters are expected in the south, whilst the northwest will face the opposite. Over 56% of regions are expected to experience more extreme high runoff, and over 40% face intensified low ...

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics
