A group of female participants in the 31st International Colloquium on Group Theoretical Methods in Physics that took place in Rio de Janeiro JUne 2016 have issued a statement about the difficulties they face, see here.
This text was written by two young women physicists who took part in an informal meeting which brought together around 20 women participants. This group of women hopes that the declaration can serve as a starting point for further actions by female physicists and mathematicians in Latin America. Sylvie Paycha was one of the organisers of the meeting.
