The home page for each section contains the statements of all the theorems in the section. In addition to the home page, each section has a page of definitions of terms which are introduced in the section and proofs of the theorems in the section. The theorem numbers in the home page are links to the proofs of the theorems. Each proof begins with a statement of the theorem, and the theorem numbers in the statement of the proofs are links back to the statement of the theorem in the home page for the section. At the end of each proof, there is a link to the proof of the next theorem in order to provide the user with additional navigational possibilities.
Web publishing provides some unique opportunities for presentation of Mathematical material.
Whenever a word appears in a proof which has a definition, there is a link to the definition. Whenever there is a reference to a previous theorem, there is a link to the proof of that theorem. The challenges of producing mathematical symbols on web pages has been solved by presenting some of the more challenging formulas as graphics, specifically gifs. If your browser is set to use a 12 point New York font, the interface between text and graphics will be much more seamless. The same background is used for all the pages in this web site.
