Preprints and Publications of Indira Chatterji
Part of this material is based upon work supported by the National Science Foundation under
Grant No. 0405032 and
CAREER Grant No. 0644613 as well as by the
Swiss National Funds Grant PA002-101406, the French CNRS ANR grant JC_318197 QuantiT ,
ANR-14-CE25-0004 GAMME and l'Institut Universitaire de France (IUF).
Any opinions, findings and conclusions or recomendations expressed in this material are those of the author(s) and do not necessarily reflect
the views of the National Science Foundation (NSF). Nor those of the Swiss National Funds, of the CNRS and IUF, I suppose, although I didn't check with them and they didn't ask me to write that.
Most of my preprints are on the ArXiV as well, but some of the published versions are below.
