The Congress on Logic, Methodology and Philosophy of Science and Technology (CLMPST) has been held every four years since the 1960s. It is a large Congress with (this year I believe) over 800 participants expected and running over 6 days: 5th – 10th August 2019.
The main website for the Congress is http://clmpst2019.flu.cas.cz/
There are 20 sections, the Bolzano Symposium is within the section B6 on History of Philosophy of Science. We had ten papers submitted and all have been accepted. We do not yet know the day(s) when our Symposium will be scheduled.
The Bolzano Symposium is entitled
Bolzano’s mathematics and the general methodology of the sciences
