Linear or linearizable first-order delay ordinary differential equations and their Lie point symmetries
Vladimir A. Dorodnitsyn, Roman Kozlov, Sergey V. Meleshko +1
A previous article was devoted to an analysis of the symmetry properties of a class of first-order delay ordinary differential systems (DODSs). Here we concentrate on linear DODSs.…
Lie group classification of first-order delay ordinary differential equations
Vladimir A. Dorodnitsyn, Roman Kozlov, Sergey V. Meleshko +1
A group classification of first-order delay ordinary differential equation (DODE) accompanied by an equation for delay parameter (delay relation) is presented. A subset of such sys…
Application of the admitted Lie group of the \\ classical Boltzmann equation to classification of the \\ Boltzmann equation with a source term
Adisak Karnbanjong, Amornrat Suriyawichitseranee, Yurii N. Grigoriev +1
The classical Boltzmann equation is an integro-differential equation which describes the time evolution of rarefied gas in terms of a molecular distribution function. For some kine…
