Best constants for Moser-Trudinger inequalities, fundamental solutions and one-parameter representation formulas on groups of Heisenberg type
In the present paper, the authors derive fundamental solutions, representation formulas and a Moser-Trudinger inequality for Sobolev functions in the setting of groups of Heisenberg type. The problem of sharp constants in Moser-Trudinger inequalities is addressed.
