标题： Branes in String/M-Theory

摘要： 这是在北京(2006)举办的亚太初级学校关于超弦和相关主题的讲座的讲义，以及在南京(2023)第三届弦、场和全息夏季学校中这些讲座的扩展版本。 它旨在从历史和教学的角度，阐述在所谓的第二次弦论革命早期阶段，寻找1/2 BPS扩展弦孤子的发展情况，在此之前这些对象被认为与弦无关。 还讨论了与膜/反膜系统或非BPS系统相关的非超对称解。 显示英文摘要

摘要： This is the writeup of lectures delivered in Asian Pacific introductory school on superstring and the related topics in Beijing (2006) and the expanded version of these lectures in the 3rd summer school on strings, fields and holography in Nanjing (2023). It intends to give a historical as well as a pedagogical account of the development in finding the 1/2 BPS extended string solitons in the early stage of the so-called second string revolution before which those objects were thought to be unrelated to strings. Non-susy solutions which are related to brane/anti brane systems or non-BPS systems are also discussed.
