Now, if someone gives β and wants to find γ, then γ is the curve satisfying the differential equation γ ′ ( t) = ( L γ ( t)) ∗ β ( t) and then as I understand, the solution to this equation is the path-ordered exponential.
SURREAL ORDERED EXPONENTIAL FIELDS - Cambridge Core
WebIn mathematics, an ordered exponential field is an ordered field together with a function which generalises the idea of exponential functions on the ordered field of real numbers. … The ordered exponential, also called the path-ordered exponential, is a mathematical operation defined in non-commutative algebras, equivalent to the exponential of the integral in the commutative algebras. In practice the ordered exponential is used in matrix and operator algebras.

WebThe idea comes mainly from papers [ 1, 2 ], which concern exponential-type operators and semi-exponential operators. In general, the exponential-type operators, introduced in [ 1 ], are considered an interesting subject for many authors. The authors examine approximation properties of these operators for functions from different function spaces. WebOrdered exponential From Wikipedia, the free encyclopedia . The ordered exponential, also called the path-ordered exponential, is a mathematical operation defined in non … WebBy using analogy with the smooth case, we defined a discrete Lagrangian density through the use of exponential functions, and derived its Hamiltonian by Legendre transform. This led to a discrete Hamiltonian system, the symplectic forms of … circle empires rivals forces of nature
