(hamiltonian flows on symplectic manifolds) and quantum mechanics (unitary flows on Hilbert spaces). At the same time, this obviously shouldn't be taken as a substitute for a more rigorous treatment of linear algebra. [H,a ] = a [H,a] = a [a,a] = 1 So these four operators, H = aa, a, a, 1, can span a Lie algebra, because the commutator satisfies closure and Jacobi's identity. | Find, read and cite all the research you need on .

Lie algebras and quantum mechanics by Hermann, Robert, 1970, W. A. Benjamin edition, in English In mathematics, a Lie algebra (pronounced / li / LEE) is a vector space together with an operation called the Lie bracket, an alternating bilinear map , that satisfies the Jacobi identity. Linear algebra is the branch of mathematics concerning linear equations such as. which are smooth manifolds, like a sphere. In this way, the problem which was open at the start of the 1980s of finding true examples of Hopf algebras was given a physical interpretation as being equivalent to finding quantum-mechanical systems reconciled with curvature, and the equations that governed this were the matched pair ones ( Majid 1988 ). Arnold Neumaier, Dennis Westra The goal of this book is to present classical mechanics, quantum mechanics, and statistical mechanics in an almost completely algebraic setting, thereby introducing mathematicians, physicists, and engineers to the ideas relating classical and quantum mechanics with Lie algebras and Lie groups.

Answer: Lie groups and Lie algebras give us the ability to study types of complex estimation issues and action recognition in a fairly efficient way. We know that in the quantum harmonic oscillator H = aa, a, a, 1 will span a Lie algebra, where a,a are the annihilation and creation operators, and H is the Hamiltonian operator. 32 Citations.
