Propagation of high peaks for the space-time fractional stochastic partial differential equations
Ngartelbaye Guerngar, Erkan Nane
We study the space-time nonlinear fractional stochastic heat equation driven by a space-time white noise, \begin{align*} \partial_t^βu(t,x)=-(-Δ)^{α/2}u(t,x)+I_t^{1-β}\Big[σ(u(t,x)…
Distributed-order space-time fractional diffusions in bounded domains
Ngartelbaye Guerngar, James McCormick
We provide explicit classical solutions and stochastic analogues for distributed-order space-time fractional diffusion equations on bounded domains with zero exterior boundary cond…
Simultaneous inversion for the fractional exponents in the space-time fractional diffusion equation
Ngartelbaye Guerngar, Erkan Nane, Ramazan Tinatztepe +2
In this article, we consider the space-time fractional (nonlocal) equation characterizing the so-called "double-scale" anomalous diffusion $$\partial_t^βu(t, x) = -(-Δ)^{α/2}u(t,x)…
A uniqueness determination of the fractional exponents in a three-parameter fractional diffusion
Ngartelbaye Guerngar, Erkan Nane, Süleyman Ulusoy +1
In this article, we consider the space-time Fractional (nonlocal) diffusion equation where $\partial…
