AbstractWe identify sufficient conditions under which evolution equations for probability density functions (PDF) of random concentrations are equivalent to Fokker–Planck…

AbstractIn this note we consider a linear and positive compound approximation operator of D.D. Stancu type depending of several parameters.…

AbstractIn the present note, we study a certain Durrmeyer type integral modification of Bernstein polynomials. We investigate simultaneous approximation and…

AbstractThe stochastic processes of finite length defined by recurrence relations request additional relations specifying the first terms of the process analogously to…

AbstractEvolution equations for probability density functions (PDFs) and filtered density functions (FDFs) of random species concentrations weighted by conserved scalars…

AbstractThe log returns of financial time series are usually modeled by means of the stationary GARCH(1,1) stochastic process or its…

AbstractA preliminary essential procedure in time series analysis is the separation of the deterministic component from the random one. If…

AbstractProbability density function (PDF) methods are a promising alternative to predicting the transport of solutes in groundwater under uncertainty. They…

AbstractThe time evolution of a physical quantity associated with a thermodynamic system whose equilibrium fluctuations are modulated in amplitude by…

AbstractThe Gaussian white noise modulated in amplitude is defined as the product of a Gaussian white noise and a slowly…
