The name "Chebyshev" is well known in numerical computation in mathematics, science, and engineering. This Web site lists 207 variants in its transliteration from the Cyrillic alphabet to the Roman one: https://mathreader.livejournal.com/9239.html The MathSciNet and zbMATH databases each record more than 4300 publications with "Chebyshev" in their titles. Alas, no online publication database that I know of permits regular expressions in searches, so finding publications that use the 200+ variants would be rather difficult. ------------------------------------------------------------------------------- - Nelson H.
