Lipschitz Graphs on Classes of Two-Step Carnot Groups
摘要
We consider two-step Carnot groups and their model cases andstudy the existence of graph mappings on them that are Lipschitz in the intrinsic sense.For the general case of two-step Carnot groups, a criterion for the Lipschitz property of a graphmapping is derived in terms of the mapping that models this graph.Examples are given that demonstrate the specificity of the necessary and sufficient conditions established.
