Classification of some first order functional differential equations with constant coefficients to solvable Lie algebras

Lobo, J.Z.; Valaulikar, Y.S. (Applications and Applied Mathematics: An International Journal. 15(2); 2020; 985-1003.)

In this paper, we shall apply symmetry analysis to some first order functional differential equations with constant coefficients. The approach used in this paper accounts for obtaining the inverse of the classification. ...
Group methods for second order delay differential equations

Lobo, J.Z.; Valaulikar, Y.S. (TWMS Journal of Applied and Engineering Mathematics. 11(4); 2021; 1194-1206.)

In this research paper, we obtain the equivalent symmetries of non-homogeneous second order delay differential equations with variable coeffcients. Group methods have been used to do this. The approach followed by us to ...
On symmetry analysis in finding solutions of the one dimensional wave equation

Lobo, J.Z.; Valaulikar, Y.S. (Proc. of Int. Conf. on Applied Mathematics & Computational Sciences (ICAMCS-2019), Ed. by: Jogendra Kumar, Seema Yadav, Fateh Singh. 2020; 133-141.)

In this paper we obtain the Lie invariance condition for second order partial differential equations. This condition is used to obtain the determining equations of the 1-dimensional wave equation with constant speed. The ...
