Intrinsic Lipschitz Graphs in Heisenberg Groups and Continuous Solutions of a Balance Equation
نویسندگان
چکیده
In this paper we provide a characterization of intrinsic Lipschitz graphs in the subRiemannian Heisenberg groups in terms of their distributional gradients. Moreover, we prove the equivalence of different notions of continuous weak solutions to the equation φy + [φ/2]t = w, where w is a bounded function.

متن کاملDistributional Solutions of Burgers’ Equation and Intrinsic Regular Graphs in Heisenberg Groups
In the present paper we will characterize the continuous distributional solutions of Burgers’ equation such as those which induce intrinsic regular graphs in the first Heisenberg group H ≡ R, endowed with a leftinvariant metric d∞ equivalent to its CarnotCarathéodory metric. We will also extend the characterization to higher Heisenberg groups H ≡ R.
متن کاملIntrinsic Lipschitz Graphs in Heisenberg Groups
In the last few years there have been a fairly large amount of work dedicated to the study of intrinsic submanifolds of various dimension and codimension inside the Heisenberg groups H or more general Carnot groups. For example intrinsically C surfaces, rectifiable sets, finite perimeter sets, various notions of convex surfaces have been studied. Here and in what follows, intrinsic will denote ...
