Lie theory (/ˈliË/ LEE) is one of the areas of mathematics, developed initially by Sophus Lie and worked out by Wilhelm Killing and Élie Cartan. The foundation of Lie theory is the exponential map relating Lie algebras to Lie groups which is called the Lie group–Lie algebra correspondence. Lie theory is a current field of research and development. This specialized field of study focuses on lie theory and its application. The Journal of Generalized Lie Theory and Applications is one of the best lie theory journals in the world. It is committed to provide the most exciting research on lie theory. Lie theory Journal is an interdisciplinary journal covers major aspects Lie theory and research.
