We deal with a class of fully coupled forward–backward stochastic differential equations (FBSDEs), driven by Teugels martingales associated with a general Lévy process. Under some assumptions on the derivatives of the coefficients, we prove the existence and uniqueness of a global solution on an arbitrarily large time interval. Moreover, we establish stability and comparison theorems for the solutions of such equations. Note that the present work extends known results proved for FBSDEs driven by a Brownian motion, by using martingale techniques related to jump processes, to overcome the lack of continuity. 相似文献

New functional dehydrophenylalanines 3 were prepared from β‐amino alcohols 1 in a two‐step reaction sequence. The synthesis involved chlorination of the starting amino alcohols 1 to afford the intermediate erythro β‐chloroamines 2 . Treatment of the latter with an appropriate base led to a highly stereoselective elimination reaction, giving the corresponding (E)‐dehydrophenylalanine derivatives 3 in high yields. © 2011 Wiley Periodicals, Inc.

This article presents the results of experimental and theoretical studies of the vO H and vO D band shapes in the polarized infrared spectra of 3‐thiophenic acid crystals measured at room temperature and at 77 K. The line shapes are studied theoretically within the framework of the anharmonic coupling theory, Davydov coupling, Fermi resonance, direct and indirect damping, as well as the selection rule breaking mechanism for forbidden transitions. The adiabatic approximation allowing to separate the high‐frequency motion from the slow one of the H‐bond bridge is performed for each separate H‐bond bridge of the dimer and a strong nonadiabatic correction is introduced via the resonant exchange between the fast‐mode excited states of the two moieties. The spectral density is obtained within the linear response theory by Fourier transform of the damped autocorrelation functions. The approach correctly fits the experimental line shape of the hydrogenated compound and predicts satisfactorily the evolution in the line shapes with temperature and the change in the line shape with isotopic substitution. © 2009 Wiley Periodicals, Inc.

The article reports a numerical study of entropy generation in double-diffusive convection through a square porous cavity
saturated with a binary perfect gas mixture and submitted to horizontal thermal and concentration gradients. The analysis
is performed using Darcy–Brinkman formulation with the Boussinesq approximation. The set of coupled equations of mass, momentum,
energy and species conservation are solved using the control volume finite-element method. Effects of the Darcy number, the
porosity and the thermal porous Rayleigh number on entropy generation are studied. It was found that entropy generation considerably
depends on the Darcy number. Porosity induces the increase of entropy generation, especially at higher values of thermal porous
Rayleigh number. 相似文献

We obtain sufficient conditions for the existence and uniqueness of a positive compact almost automorphic solution to a logistic equation with discrete and continuous delay. Moreover, we provide a counterexample to some results in literature which deal with the uniqueness of almost periodic solutions to logistic type equations. 相似文献
