About me
Just a mathematics student with a broad interest, trying to make mathematics more accessible.

For you, reader

 * Ever wondered how all those nice diagrams made it to your book? Check out the xymatrix package documentation.

My personal templates, sandboxes and the like:

User:Lord_Farin/common.js is the .js file I use to develop new functionality in.

User:Lord_Farin/Sandbox is my sandbox, which is used to test functionality, and prepare/attempt pages and structures. May have subpages attached.

User:Lord_Farin/SandboxTemplate is my sandbox template, in which I experiment with templates.

User:Lord Farin/Proof Structures is the place for proof templates I (and hopefully more people) tend to use.

User:Lord Farin/Tableau Proof Rules is where I keep templates for all allowed inferences in tableau proofs. This may appear as a bona fide page in the future.

User:Lord_Farin/Archive is a mixture between a graveyard and a safe haven for stuff which has nowhere else to go.

Category:Lord_Farin's Stubs is the Category for pages I plan to finish later on.

User:Lord Farin/Long-Term Projects is the place for things that are on even longer tracks than those in above Category; these are often meta-structural.

Landmarks
I am particularly fond of the following contributions (all of which hence are my own work; i.e., I didn't copy the proof from some source):


 * Absolutely Convergent Generalized Sum Converges
 * Hilbert Space Direct Sum is Hilbert Space
 * Definition:Magma of Sets, an encapsulating notion from my hand

Too lazy
These results are mostly trivial and I can't be bothered putting them up right now; please, feel free.
