On Computing Linearizing Coordinates From Symmetry Algebra
Sajid Ali, Hassan Azad, Said Waqas Shah +1
A characterization of the symmetry algebra of the th order ordinary differential equations (ODEs) with maximal symmetry and all third order linearizable ODEs is given. This is u…

Higher order self-adjoint operators with polynomial coefficients
H. Azad, A. Laradji, M. T. Mustafa
Algebraic and analytic aspects of self-adjoint operators of order four or more with polynomial coefficients are investigated. As a consequence, a systematic way of constructing suc…

Sturm-Liouville Theory and Orthogonal Functions
H. Azad, M. T. Mustafa
We revisit basics of classical Sturm-Liouville theory and, as an application, recover Bochner's classification of second order ODEs with polynomial coefficients and polynomial solu…
