Title: Growth properties of solutions of complex differential equations with entire coefficients of finite (alpha,beta,gamma)-order Authors: Benharrat Belaidi (Univ. of Mostaganem (UMAB), Mostaganem, Algeria) Tanmay Biswas (R. N. Tagore Road, West Bengal, India) Abstract: In this article, we investigate the complex higher order linear differential equations in which the coefficients are entire functions of (α, β, γ)-order and obtain some results which improve and generalize some previous results of Tu et al. [29] as well as Belaidi [1, 2, 3]. Submitted July 22, 2023. Published March 11, 2023. Math Subject Classifications: 30D35, 34M10. Key Words: Complex differential equations; (alpha, beta, gamma)-order; growth of solutions.
