TY - JOUR TI - Conformable fractional derivative and its application to fractional Klein-Gordon equation AU - Wang Kangle AU - Yao Shaowen JN - Thermal Science PY - 2019 VL - 23 IS - 6 SP - 3745 EP - 3749 PT - Article AB - This paper adopts conformable fractional derivative to describe the fractional Klein-Gordon equations. The conformable fractional derivative is a new simple well-behaved definition. The fractional complex transform and variational iteration method are used to solve the fractional equation. The result shows that the proposed technology is very powerful and efficient for fractional differential equations.
