WebNov 5, 2015 · We obtain a pointwise integro-differential formula for $(\partial_t-\Delta)^su(t,x)$ and parabolic maximum principles. A novel extension problem to characterize this nonlocal equation with a local degenerate parabolic equation is proved.

WebHe essentially argues that more than 1 timelike dimension would remove our ability to predict the future from the present. In math terms, more than one timelike dimension would render our differential equations ultrahyperbolic, and ultrahyperbolic PDEs are not well posed for initial data given along spacelike hypersurfaces. WebIf Q can be transformed into ± (ξ 2 1 + • • • + ξ 2 n-1 - ξ 2 n ), the equation is called normal hyperbolic. Elliptic and normal hyperbolic equations constitute the two types which have …
WebWe give a random field solution to this equation by defining a process via a kind of Feynman–Kac representation which solves a stochastic partial differential equation such that its Hopf–Cole transformation solves Burgers' equation.
