These notes are based on the string theory lecture course by Prof. Amihay Hanany, taught at Imperial College London in 2025. While they broadly follow the structure of the course, at times I decided to …

Given an initial and final shape for the string, all possible trajectories are surfaces that describe the motion of the initial shape into the final one. Topologically these surfaces are cylinders.

Original handout written by Neal Kanodia and Steve Jacobson. One of the most useful data types supplied in the C++ libraries is the string. A string is a variable that stores a sequence of letters or …

Jun 28, 2024 · Exact String Matching: Given a string S and a string/pattern T, Is T a substring of S? If so, how many times does T appear? ⇒ Find the positions of all occurrences of the pattern T in S.

We will use the model to find the string spectrum, first for open strings then closed. Spectrum? What spectrum? What distinguishes one string from another is the wave pattern on the string. Strings can …

A number of more recent topics in string theory are not covered in these notes, including D-branes (except in Appendix C), the AdS/CFT correspondence, M-theory and topological string theory to …

Lots of string processing functions for copying one string to another comparing two strings determining the length of a string concatenating two strings
