Expansions of the solutions of the general Heun equation in terms of the incomplete Beta functions

T. A. Shahverdyan, V. M. Red'kov, A. M. Ishkhanyan

Applying the approach based on the equation for the derivative, we construct several expansions of the solutions of the general Heun equation in terms of the incomplete Beta functi…

New relations for the derivative of the confluent Heun function

V. A. Shahnazaryan, T. A. Ishkhanyan, T. A. Shahverdyan +1

The cases when the equation for the derivative of the confluent Heun function has only three singularities (in general, the equation has four such points) are examined. It is shown…
