科研成果:
(1)程金发教授代表性工作之一是分数阶差分方程理论的探索和开创性研究:首次创造性地提出了一种新的分数阶差分,分数阶和分,以及分数阶差分方程的定义,系统深入地研究了分数差分及分数和分之间的基础性质和分数阶差分方程一系列基础定理,这些重要的结果,都被系统总结到我们的《分数阶差分方程理论》专著中,这也是国内外第一部该领域的著作,因此在国内外产生了重要的积极影响。需要特别指出的是: 运用我们的这种新的定义,使得求解分数阶差分方程得以成功实现,也显现了建立分数阶差分方程理论的光明前景,从而实质上开拓了分数阶差分方程理论这个全新领域的研究方向。目前国内外同行已经逐步了解并认识我们的这种有益的探索和开创性工作,如今,在国内外同行们的共同研究发展下,分数阶差分与和分定义,以及分数阶差分方程一些基础知识与基本理论,已经为业内同行所熟悉,并积极加入到分数阶差分方程理论的研究与应用中来。
(2)程金发教授代表性工作之二是致力于研究探索非一致格子上复超几何差分方程和非一致格子上离散分数阶微积分的研究。 非一致格子复差分方程中,尤以非一致格子上高斯型超几何复差分方程最为著名,它分别由美国科学院数学院士Askey和苏联数学院士Nikiforov等所开拓,是一类最具一般性的复超几何方程,许多特殊函数和正交函数都来自于该方程,美俄两大数学门派都取得的许多非凡的重要成果。目前国内外绝大多数研究者一般从事一致格子的实差分研究,但我们认为非一致格子的复差分研究难度更大更具挑战性,也更与国际前沿接轨。在非一致格子上,复分数阶和分以及差分又如何定义?这目前在国际上都是一个艰难深刻的课题,是最一般性的分数阶差分问题,因为即使在正整数阶差分,Nikiforov在求解非一致格子超几何方程的Rodrigues公式型解时,率先得到了这个公式,这都是一个非凡的成果。如今我们经过长期的酝酿积累和潜心探索,已经能够给出非一致格子上分数阶和分以及差分合理的定义;得到著名的Euler Beta公式以及Cauchy Beta复积分公式在非一致格子上的模拟。这些新概念新定义目前在国际上尚属首次,这是一个较大的创新。利用非一致格子上分数阶微积分,有助于深入研究非一致格子超几何差分方程的解,同时相信也能引出许多新的更困难有趣的问题,激发国际或国内一流学者同行参与钻研,为非一致格子上复分数阶差分方程和特殊函数的研究打开一扇崭新大门。我们一些相关的科研成果,已经被系统总结到专著《非一致格子超几何方程与分数阶差和分》中,于2021年在科学出版社出版。
