论文摘要
这是基于von Neumann-Bernays-Gödel的公理（短暂的NBG）的简短介绍课程。该文本可以用作数学基础的讲座课程的基础，并包含一个合理的最低限度，而数学的好（研究生）学生应该知道这项科学的基础。
This is a short introductory course to Set Theory, based on axioms of von Neumann--Bernays--Gödel (briefly NBG). The text can be used as a base for a lecture course in Foundations of Mathematics, and contains a reasonable minimum which a good (post-graduate) student in Mathematics should know about foundations of this science.
