Description
Springer Stratified Lie Groups And Potential Theory For Their Sub-Laplacians by Andrea Bonfiglioli
This book provides an extensive treatment of Potential Theory for sub-Laplacians on stratified Lie groups. It also provides a largely self-contained presentation of stratified Lie groups, and of their Lie algebra of left-invariant vector fields. The presentation is accessible to graduate students and requires no specialized knowledge in algebra or differential geometry._x000D_ _x000D_
