TY - JOUR TI - On nabla discrete fractional calculus operator for a modified Bessel equation AU - Yilmazer Resat AU - Ozturk Okkes JN - Thermal Science PY - 2018 VL - 22 IS - 11 SP - 203 EP - 209 PT - Article AB - In thermal sciences, it is possible to encounter topics such as Bessel beams, Bessel functions or Bessel equations. In this work, we also present new discrete fractional solutions of the modified Bessel differential equation by means of the nabla-discrete fractional calculus operator. We consider homogeneous and non-homogeneous modified Bessel differential equation. So, we acquire four new solutions of these equations in the discrete fractional forms via a newly developed method
