We will state a sufficient condition for the existence of density for the marginals of a delayed diffusion.

the rank of Lie algebra generated by the operators X0,, Xr is equal to m. In his paper (1967) he provides an example of uxx + xuy − ut = 0 which satisfies that. Hormander type con- ditions in the scale of Orlicz spaces are assumed on the kernels.

Consider a slight modiflcation to the above 1-D setup. We’ll change variables from the nice Cartesian coordinate x to another coordinate q deflned by, say, x(q) = Kq5, or equivalently q(x) = (x=K)1=5. In the present work we prove a version of Hormander’s theorem for solutions of differential¨ equations driven by a fractional Brownian motion.

Whether you're driving locally or embarking on a road trip, it helps to know about driving conditions. You can check traffic conditions before you leave, and then you can also keep tabs on what's happening on your mobile device.

In this way, we obtain relative versions of the isoperimetric estimates in [FGaWl], [FGaW2], which are derived by using Sobolev's Li, K 2018, ' Sparse Domination Theorem for Multilinear Singular Integral Operators with L-r-Hormander Condition ', Michigan Mathematical Journal, vol. 67, no. 2, pp. 253-265. 411 Chapel Drive Durham, NC 27708 (919) 660-5870 Perkins Library Service Desk The condition only provides information on the product of distributions that are relevant for pdes - those that satisfy the Lebiniz rule. For example, the Heaviside function can be multiplied with itself but the Lebniz rule does not hold for the square of Heaviside function.

Hörmander's Theorem 1.1 gives a sufficient condition for hypoellipticity.
