In order to support public research, I now submit my articles only to (free) academic journals.

My research works are 100% funded by public institutions; we edit and refer freely the research articles for publication, which often appear in electronic format.
So there is no reason for the Government to pay high fees to private edition compagnies so that the mathematical community  can have an acces to its own work.
