    本文主要研究若干q-算子的逼近性质,内容包含三个方面,一是Kantorovich型q-BBH算子、修正的Durrmeyer型q-Baskakov算子、修正的Kantorovich型q-Sz\'{a}sz算子、修正的q-Gamma算子等q-算子的逼近性质;二是Durrmeyer型q-BBH算子及修正的Kantorovich型q-Sz\'{a}sz算子的统计逼近性质;三是复Gamma算子在紧圆盘上的逼近性质. 全文共分为五章.第一章,首先引入本文所涉及到的基本定义和句号,然后综述了本文所研究内容的相关背景及研究进展,最后是本文的主要工作概述. 第二章,定义了两类q-型算子,分别为Dur...This paper focuses on a study about properties of some q-operators, it comprises three parts. Part one, approximation properties of Kantorovich type q-BBH operators, modified Durrmeyer type qq-Baskakov operators, modified Kantorovich type q-Sz\'{a}sz operators and modified Gamma operators; Part two, statistical approximation properties of Durrmeyer type q-BBH operators and modified Kantorov...学位:理学博士院系专业:数学科学学院_计算数学学号:1902010015395
