In the realm of algebraic structures, Lie algebras and their siblings, Lie triple systems, hold significant importance. While Lie algebras have garnered considerable attention due to their applications in physics and mathematics, Lie triple systems often stand in their shadow despite their intriguing properties and applications. In this article, we embark on a journey to explore Lie triple systems, their fundamental concepts, properties and applications, shedding light on these lesser-known yet fascinating structures.
A subclass of Lie triple systems, Jordan triple systems, has garnered significant attention due to their close connection with Jordan algebras. A Jordan triple system is a vector space equipped with a ternary operation satisfying the Jordan identity:
[x,y,[x,x,y]]=0
for all x, y in the vector space. Jordan triple systems arise naturally from the structure of Jordan algebras and their study has led to important developments in algebra and geometry [1].
Octonions, the non-associative extension of quaternions, give rise to Lie triple systems known as octonionic triple systems. These systems play a crucial role in the theory of exceptional Lie algebras and have connections to the geometry of octonionic projective planes. Studying octonionic triple systems provides insights into the rich algebraic structures underlying the exceptional Lie groups and their representations. Lie triple systems arise naturally in the study of symmetric spaces and homogeneous spaces. Symmetric spaces are spaces equipped with a symmetric bilinear form that exhibits certain symmetries. Lie triple systems provide a framework for understanding the structure of symmetric spaces and their geometric properties. Moreover, the theory of symmetric spaces has deep connections to differential geometry, Lie theory and representation theory.
Lie triple systems find applications in the study of integrable systems and soliton equations. Integrable systems are systems of partial differential equations that possess sufficiently many conserved quantities, allowing for their exact solution [2]. Lie triple systems provide a framework for understanding the underlying algebraic structures of integrable systems and have been instrumental in the study of soliton equations, such as the Korteweg–de Vries equation and the sine-Gordon equation. Lie triple systems play a crucial role in the study of supersymmetric quantum mechanics. N=2 supersymmetry, the algebra of supersymmetry transformations forms a Lie triple system, providing a mathematical framework for understanding the underlying symmetries of supersymmetric quantum systems. Lie triple systems also appear in the context of extended supersymmetry and have applications in the study of supersymmetric field theories and string theory.
One of the key properties of Lie triple systems is their connection to Jordan algebras. Lie triple systems arise naturally from the structure of Jordan algebras and there exists a close relationship between the two. For instance, every Jordan algebra gives rise to a Lie triple system by defining the ternary operation as the Jordan triple product. Moreover, Lie triple systems exhibit intriguing symmetries and structures [3,4]. For example, the Freudenthal construction associates to every Jordan algebra a Lie triple system with a certain amount of symmetry, known as the "Freudenthal magic square". This construction has deep connections to the theory of exceptional Lie algebras and plays a crucial role in their classification. Furthermore, Lie triple systems find applications in various areas of mathematics and physics. In differential geometry, Lie triple systems arise naturally in the study of symmetric spaces and homogeneous spaces [5]. They also play a role in the theory of algebraic groups and their representations. Moreover, Lie triple systems find applications in mathematical physics, particularly in the study of integrable systems. Integrable systems are systems of differential equations that possess sufficiently many conserved quantities, allowing for their exact solution. Lie triple systems provide a framework for understanding the underlying algebraic structures of integrable systems and have been instrumental in their study.
Lie triple systems represent a fascinating area of study within algebra and its applications. Despite being overshadowed by their more well-known sibling, Lie algebras, Lie triple systems possess rich mathematical structures and find applications in various areas of mathematics and physics. Understanding Lie triple systems not only deepens our understanding of algebraic structures but also sheds light on the underlying mathematical structures of the universe. As we continue to explore the intricacies of Lie triple systems, we uncover new connections and applications, reaffirming their importance in the landscape of mathematics and physics. Lie triple systems represent a rich and diverse area of study within algebra and its applications. From their connections to Jordan algebras and exceptional Lie groups to their applications in differential geometry, mathematical physics and quantum mechanics, Lie triple systems offer a deep and profound insight into the underlying mathematical structures of the universe. As researchers continue to explore the intricacies of Lie triple systems, we can expect further developments that will deepen our understanding of algebraic structures and their applications in mathematics and physics.
