This means something. Any editor can be used to write latex code, but it is desirable to use an efficient one (Vi(m), Emacs, WinEdt, TeXnicCenter, Kile, . ). This saves a lot of time. It is interesting to remark that there are (perl) scripts that continuously run latex. See http://magic.aladdin.cs.cmu.edu/2007/11/06/continuous-latex- compilation-using-latexmk/ It is convenient to take a look at the short document “An essential guide to LATEX2e usage” about bad habits. ftp://ftp.tex.ac.uk/tex-archive/info/l2tabu/english/l2tabuen.pdf Félix Bou (IIIA - CSIC) Computer Guidance in Logical Research 17th October 2008, Barcelona 2 / 5 A great auxiliary tool is BibTeX This helps to citations inside a LATEXdocument. You have to write in the code something like \bibliographystyle{alpha} %% or plain, etc. \bibliography{logalg} where “logalg.bib” is for instance the name of the database. There are a lot of webpages where you can download citations in bibtex format. For example, Mathscinet, Zentralblatt, The ACM Digital Library, etc. There are great bibtex database managers like JabRef, Pybliographer and Bibdesk. They allow to synchronize your database with files inside your computer. This provides a really efficient way to find and organize your e-papers and e-books.

A helpful indexes are the ones given in http://www-formal.stanford.edu/clt/ARS/systems.html and http://ar.colognet.org/tools.php We will take a carefull look at the pair Prover9-Mace4 http://www.cs.unm.edu/ mccune/prover9/ I also want to mention SEM (system for enumerating finite models) http://www.cs.uiowa.edu/ hzhang/sem.html Félix Bou (IIIA - CSIC) Computer Guidance in Logical Research 17th October 2008, Barcelona 4 / 5 The Universal Algebra Calculator UACalc It is available at http://www.uacalc.org/ Among other things it can compute all congruences (of a finite algebra) and find the free algebra finitely generated (of the variety generated by a finite algebra).
