Symmetry Properties of Autonomous Integrating Factors [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2005 We study the symmetry properties of autonomous integrating factors from an algebraic point of view. The symmetries are delineated for the resulting integrals treated as equations and symmetries of the integrals treated as functions or configurational ...

Integrating Factor Models [PDF]
The Journal of Finance, 2021 ABSTRACTThis paper develops a comprehensive framework to address uncertainty about the correct factor model. Asset pricing inferences draw on a composite model that integrates over competing factor models weighted by posterior probabilities. Evidence shows that unconditional models record near‐zero probabilities, while postearnings announcement drift ...

Finding Liouvillian first integrals of rational ODEs of any order in finite terms [PDF]
, 2005 It is known, due to Mordukhai-Boltovski, Ritt, Prelle, Singer, Christopher and others, that if a given rational ODE has a Liouvillian first integral then the corresponding integrating factor of the ODE must be of a very special form of a product of ...

Mathematica Bohemica, 1994 Summary: The problem of integrating factor for ordinary differential equations is investigated. Conditions are given which guarantee that each solution of \(\partial_ 1 F(x,y) + y'\partial_ 2 F(x,y) = 0\) is also a solution of \(M(x,y)+ y' N(x, y)= 0\) where \(\partial_ 1 F= \mu M\) and \(\partial_ 2 F= \mu N\).
