弦理论简介(A Brief Introduction to String Theory) 只看楼主收藏回复 大江大海_1949 酷 3 长久以来,我们生活在熟悉的三维世界,无论什么物体,无论在哪儿,可以左右、上下、前后移动,但电影中的一切有所不同。尽管屏幕中的角色看起来是三维的,其实它们仅“困在”二维空间,因为电影屏幕没有前后之分。更直白地说,电影中的“三

The goal is to provide a practical, "how-to" manual on string theory, string model-building, and string phenomenology with a minimum of mathematics. These notes consist of Part I of these lectures, which cover the construction of bosonic strings, superstrings, and heterotic strings prior to ...
1. Introduction A parameterized string (p-string) is composed of symbols from a constant alphabet Σ and a parameter alphabet Π. Two p-strings S and T are parameterized matches (p-matches) if (1) all of the constant symbols match exactly, i.e. if S[i],T[i]∈Σ then S[i]=T[i...
Introduction and summary Fifty years ago this month, 't Hooft argued [1] that the large N limit of SU(N ) gauge theories, keeping fixed the 't Hooft coupling λ = gY2 MN , could be equivalent to a string theory with string coupling gstr ≃ 1/N , such that the string theory ...
如果一定要学群论,我会考虑Zee的Group Theory in a Nutshell。 当然,如果有人和你大谈微分几何和数学基础,你可以向他/她推荐Spivak的A Comprehensive Introduction to Differential Geometry,并且敦促他/她全部读完本书及其前置之后再开始学习物理。 数学进阶 还不满足?也许你会合适学数学物理!数学物理是往往数学或者数...
1d shows that many documents are rather short, e.g. 25% of the documents are below 14575 characters or 3181 words. However, 200 documents are longer than 1 million characters, 49 documents are longer than 10 million characters and the longest documents are several hundred million words or ...
Other students have obtained the desired result from specialization of more complex programs, either independently or after only a short presentation of the language features. As a more realistic test, our declarative approach has also been used by an engineer at Philips to customize industrial code...
Third, it is important to acknowledge that our models primarily focus on capturing the dynamics of reading and citing within the short-to-medium term. Over a longer period, one should consider additional dynamics such as the scientific obsolescence of older works, the diminishing weight of previous...
The goal of these notes is to give a short introduction to Fukaya categories and some of their applications. The first half of the text is devoted to a brief review of Lagrangian Floer (co)homology and product structures. Then we introduce the Fukaya category (informally and without a lot ...
