On the integration of Ito equations with a random or a W-symmetry
G Gaeta - Journal of Mathematical Physics, 2023 - pubs.aip.org
Symmetries can be used to integrate scalar Ito equation–or reduce systems of such
equations–by the Kozlov substitution, ie passing to symmetry adapted coordinates. While …
