The article presents a series solution approach for the "deformed" double-confluent Heun equation, which arises from the radial part of the Klein-Gordon equation in the background of the Nutku-Ghezelbash-Kumar metric. The method involves the convolution of series expansions to handle the non-polynomial coefficients in the equation.
