A priori bounds for the generalised parabolic Anderson model

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract We show a priori bounds for solutions to (∂t−Δ)u=σ(u)ξ$(\partial _t - \Delta) u = \sigma (u) \xi$ in finite volume in the framework of Hairer's Regularity Structures [Invent Math 198:269–504, 2014]. We assume σ∈Cb2(R)$\sigma \in C_b^2 (\mathbb {R})$ and that ξ$\xi$ is of negative Hölder regularity of order −1−κ$- 1 - \kappa$ where κ<κ¯$\kappa <

Almost Periodic (Type) Solutions to Parabolic Cauchy Inverse Problems

open access: yesAbstract and Applied Analysis, 2012
We first show the existence and uniqueness of (pseudo) almost periodic solutions of some types of parabolic equations. Then, we apply the results to a type of Cauchy parabolic inverse problems and show the existence, uniqueness, and stability.

Symmetrization for fractional Neumann problems

open access: yes, 2016
In this paper we complement the program concerning the application of symmetrization methods to nonlocal PDEs by providing new estimates, in the sense of mass concentration comparison, for solutions to linear fractional elliptic and parabolic PDEs with ...

Damping Modification Factors for Pile–Induced Filtering Effect

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Period–dependent Damping Modification Factors are usually applied to the 5%–damped pseudo–acceleration response spectrum at free field conditions to derive the seismic demand for structures with damping ratio other than 5%. Likewise, the response spectrum at the foundation level of pile–supported structures may differ from the free field ...

Allen-Cahn and Cahn-Hilliard variational inequalities solved with Optimization Techniques [PDF]

open access: yes, 2010
Parabolic variational inequalities of Allen-Cahn and Cahn- Hilliard type are solved using methods involving constrained optimization. Time discrete variants are formulated with the help of Lagrange multipliers for local and non-local equality and ...

KOSTANT'S PROBLEM AND PARABOLIC SUBGROUPS [PDF]

open access: yesGlasgow Mathematical Journal, 2009
AbstractLet be a finite dimensional complex semi-simple Lie algebra with Weyl group W and simple reflections S. For I ⊆ S let I be the corresponding semi-simple subalgebra of . Denote by WI the Weyl group of I and let w○ and wI○ be the longest elements of W and WI, respectively. In this paper we show that the answer to Kostant's problem, i.e.

Development of a Novel Modified Mean‐Line Approach for Performance Prediction of Axial Compressors

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT There is significant importance in accurate prediction of axial flow compressor characteristics at different conditions. Different techniques and models have been proposed for performance prediction of axial compressors. Because of its lower computational cost and high speed the meanline algorithm has been widely applied in preliminary design ...

Well-posedness of elliptic-parabolic differential problem with integral condition

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
In this paper, we study a class of nonlocal boundary value problems for elliptic-parabolic equations subject to integral-type conditions. Such problems naturally emerge in various physical and engineering contexts, including diffusion processes in ...
