Graph surfaces of codimension two over three-dimensional Carnot-Carathéodory spaces (Q334433)

The paper under review is a continuation of the work done by the author in [Sib. Math. J. 56, No. 5, 852--871 (2015); translation from Sib. Mat. Zh. 56, No. 5, 1068--1091 (2015; Zbl 1345.53035)] representing a development of measure theory for graph surfaces over Carnot-Carathéodory spaces. Using the polynomial sub-Riemannian differentiability property, the author investigates the area and properties of graph surfaces of codimension-two over three-dimensional Carnot-Carathéodory spaces.
