Hayk Melikyan (North Carolina Central University) "New Variations on the Theme of Maximal Subalgebras"

**Abstract:**

The description of maximal subsystems of any algebraic system is an essential and important step toward the structural characterization of the system. In Lie Theory there are a number of well-known problems where the maximal subsystems play a crucial role.

In this talk we will discuss results and problems related to the classification of maximal sub-algebras in simple Lie algebras (superalgebras) over the fields of positive characteristics (which includes the classical simple Lie algebras and algebras (superalgebras) of Cartan type), and in-finite dimensional Lie algebras of Cartan over the field of characteristic zero.
