A Class of Noncommutative Spectra

We construct a class of noncommutative spectra and give the basic properties of the class of noncommutative spectra

Some Results about Triangular Representations of Lie Algebras

We introduce the concept of a triangular representation of a Lie algebra, give a counterpart of Ado's theorem, and discuss $2$-irreducible triangular modules over a nonreductive Lie algebra
