Theta calculus
Original research by User:Dirnstorfer alias User:Dadim. The article establishes a notation, which uses function composition in the opposite way, without explaining why it is useful. As far as I can see, nobody but the author uses this notation. Mathematical Reviews has not heard about it. Related articles by the same author are Evaluation operator (now deleted, see Votes for deletion/Evaluation operator) and Multiscale calculus (see Votes for deletion/Multiscale calculus).

 * Delete. If you click through the first external link and read the paper, it's basically been cut up and pasted in, making the article just a copy of the primary source. Show me someone using this mathematics and I'll show you a keep vote. ESkog 22:57, 17 May 2005 (UTC)

 * I'm not sure about this one. This page is cross-linked in several other notable articles. Are the entries in those articles also by the same author? Or are those researched cross-links by other contributors? Operator calculus is perfectly valid, and this just appears to be a notational form of said calculus. &mdash; RJH 15:27, 18 May 2005 (UTC)
 * What links here shows that the only pages in the main space linking to theta calculus are calculus (disambiguation) (link added by Dirnstorfer), derivative security (link added (diff) by User:213.20.164.133, who has made no other contributions) and strategy (game theory) (written by Dirnstorfer).
