Affine processes also include all Lévy processes. Informally, a process X on a state space D is affine if its characteristic function can be written as E[eiu Xt ] = eφ(t,u)+ψ(t,u) X0 for some complex-valued functions φ and ψ. The functions φ and ψ solve a system of ODEs...
Properties of the law of the martingale limit W∞ such as characteristic functions, densities, moments and characterizing stochastic fixed-point equations were studied by Chauvin, Pouyanne and Sahnoun [4], Neininger and Knape [26], as well as by Chauvin, Pouyanne and Mailler [5]. Similarly, ...

including the respective reference solutions, their characteristics, and typical challenges when dealing with this type of consolidation problem. We conclude this section with the base setting for all training processes used within this work as we combine PINNs and the PDEs underlying the consolidation ...
Therefore, any model that correctly describes the contact stiffness on the largest scale and reproduces the gradient of the surface profile on the smallest scale, is eligible for the study of frictional processes (examples of models based on the two-scale nature of frictional contacts can be ...
γ1 and γ2 introduce an exponential memory characteristic to signify the weighted importance of the preceding training observation data, leading to smooth model adaptation behavior. Their values can be set properly in the range of one and zero (i.e., 0<γ1⩽1, 0<γ2⩽1). γ1 = γ...
