I have a citation that is transliterated from Russian Cyrillic.
@book{kondratyev_radiation_1969,
address = {New York},
series = {International geophysics series},
title = {Radiation in the atmosphere},
volume = {12},
publisher = {Academic Press},
author = {Kondratyev, K. Ya.},
year = {1969},
keywords = {Atmosphere, Solar radiation, Transport theory},
}
This means that the authors second initial is 'Ya' yet when using bibtex the a gets cut off.
I even tried this with no success:
@book{kondratyev_radiation_1969,
address = {New York},
series = {International geophysics series},
title = {Radiation in the atmosphere},
volume = {12},
publisher = {Academic Press},
author = {Kondratyev, K. {Ya}.},
year = {1969},
keywords = {Atmosphere, Solar radiation, Transport theory},
}
Does anyone know how to force bibtex to treat the two letters Ya as one?

author = {Kondratyev, K. {\relax Ya}.},?

Correct me if I'm wrong, but I think it is fair to assume that if the OP indeed uses BibTeX it does not really matter which abbreviated style is used since they all rely on the same BibTeX function. – moewe Jun 13 '18 at 20:35
