Generalized Lie algebras have emerged as a vibrant and evolving field within modern mathematics, expanding the conceptual boundaries established by classical Lie algebras. Lie algebras, originally conceived to study the symmetries of differential equations and continuous groups, have played a pivotal role in the development of many areas of mathematics and theoretical physics. However, as our understanding of symmetries has grown and as new applications have emerged, the need to extend the classical framework has become increasingly apparent. Generalized Lie algebras address this need by broadening the scope of traditional Lie algebras, introducing new structures and operations that capture a wider range of algebraic phenomena. This article explores the recent developments in generalized Lie algebras, highlighting their expanding horizons and their profound implications for mathematics and physics. The classical theory of Lie algebras is built on a few fundamental principles. Lie algebra is a vector space equipped with a bilinear operation, known as the Lie bracket that satisfies two key properties antisymmetric and the Jacobi identity. These properties ensure that Lie algebras are well-suited to describe the infinitesimal symmetries of Lie groups, which in turn represent continuous symmetries of geometric and physical systems. Over the past century, Lie algebras have become a cornerstone of mathematical physics, underpinning the study of particle physics, quantum mechanics, and differential geometry.
