Space-time coupled evolution equations and their stochastic solutions

10 Mar 2019  ·  Herman John, Johnston Ifan, Toniazzi Lorenzo ·

We consider a class of space-time coupled evolution equations (CEEs), obtained by a subordination of the heat operator. Our CEEs reformulate and extend known governing equations of non-Markovian processes arising as scaling limits of continuous time random walks, with widespread applications... In particular we allow for initial conditions imposed on the past, general spatial operators on Euclidean domains and a forcing term. We prove existence, uniqueness and stochastic representation for solutions. read more
