Stochastic di erential games are considered in a non-Markovian setting. Typically, in stochastic di erential games the modulating process of the di usion equation describing the state ow is taken to be Markovian. Then Nash equilibria or other types of solution such as Pareto equilibria are constructed using Hamilton-Jacobi-Bellman (HJB) equations. But in a non-Markovian setting the HJB method i...

in this work, we have applied elzaki transform and he's homotopy perturbation method to solvepartial di erential equation (pdes) with time-fractional derivative. with help he's homotopy per-turbation, we can handle the nonlinear terms. further, we have applied this suggested he's homotopyperturbation method in order to reformulate initial value problem. some illustrative examples...

a novel and e ective method based on haar wavelets and block pulse functions(bpfs) is proposed to solve nonlinear fredholm integro-di erential equations of fractional order.the operational matrix of haar wavelets via bpfs is derived and together with haar waveletoperational matrix of fractional integration are used to transform the mentioned equation to asystem of algebraic equations. our new m...

the reservoir’s diff erential pressure. Most samples are initially humidifi ed to avoid the softening matrix eff ect of initial introduction of moisture in the pore space. Small amounts of water (less than 1% of the pore volume) can reduce the bulk and shear moduli of the rock signifi cantly. Th e data in this paper are the estimated mean properties (markers in the plots) and one standard devia...

Single preimplantation embryo mRNA diff erential display was used to study the gene expression of 2-cell,4cell, and 8-16-cell stage goat embryos produced in vitro, and 16 diff erent stage specifi c bands in total were screened. In these specifi c bands, 5 were in 2-cell stage, 4 were in 4-cell stage, and 7 were in 8-16-cell stage, respectively. Th e sequencing and alignment results suggested th...

The electronic structures of the nitrogenase active sites, FeMoco and FeVco, have been investigated by a parallel study of the holoenzymes with synthetic cubane cluster models. Using high-resolution X-ray spectroscopies coupled with density functional theory calculations, key diff erences between FeMoco and FeVco have been identifi ed, rationalizing the isozymes’ diff erential affi nity for var...

in this study we produced a new method for solving regular di erential equations with step size h and taylor series. this method analyzes a regular di erential equation with initial values and step size h. this types of equations include quadratic and cubic homogenous equations with constant coecients and cubic and second- level equations.

This paper examines the eff ect of neighborhood diversity on the nativity gap in homevalue appreciation in Australia. Specifi cally, immigrant homeowners experienced a 41.7 percent increase in median home values between 2001 and 2006, while the median value of housing owned by the native-born increased by 59.4 percent over the same period. We use a semi-parametric decomposition approach to asse...
