This page lists various auxiliary tools and programs that can hardly be classified as "high scientific achievements". At the same time, many of them have significantly simplified my "mathematical life". I hope that they may be of interest to someone else.

JSRbib

A perpetually updated annotated list of publications on the convergence of infinite matrix products and the rate of their growth/decrease as the number of factors tends to infinity.


latex2html via tex4ht

Example to novices how to transform TeX file with plenty of mathematics to HTML.


KVicTools

Here are collected some programs and scripts designed to configure support for the Russian language in MikTeX, TeX Live systems and the WinEdt editor.


BarNorm

Here are collected some scripts in the MATLAB and Python languages for constructing Barabanov norms of sets of 2x2 matrices and computing the associated characteristics.


Spectrum maximizing products

Here are collected some scripts in Wolfram Mathematica, MATLAB, and Python designed to construct examples of matrix sets {A,B} for which the BAA and BBA are spectrum maximizing products.


BibTeX to AMSBIB

When preparing manuscripts for publication in the vast majority (more than 150) of Russian mathematical journals, the portal Math-Net.Ru recommends that the bibliography be formatted in the style of AMSBIB. To simplify and unify the process of converting bibliography from the BibTeX format to the AMSBIB format, the style files amsbib.bst and amsbibs.bst are presented here, which perform such conversion automatically.


footbibx

Here, the modification footbibx.sty of the footbib.sty package is presented in which, instead of hardcoded changes to LaTeX core, a dynamic "patch" of the appropriate locations in LaTeX core is implemented using the \xpatxhcmd mechanism from the xpatch.sty package (if desired, you can use the same commands from the regexpatch.sty package). We hope that this method of making changes to LaTeX core will be less sensitive to possible future changes to LaTeX.
