The pen is mightier than the sword.
Here is a small list of mathematical symbols that you may use in papers that you publish. To the bottom left of this page is a small navigation menu, that will allow you to quickly go from section to section to search for the symbol that you need. I tried to organize the sections based on the subjects that they may be used in and use words that mathematicians use. So, the names of each of the symbols presented are not the actual names. I hope it helps you type some great papers! ^_^
Remember to include the amssymb and amsmath packages by including the line
\usepackage{amssymb,amsmath}
under your document class.
Also, this list is by no means a complete list of every symbol that you may want to use.
