Abstract

The cohomological Hall algebra is an associative algebra associated to an abelian category, and models an algebra of BPS states in 4d HT theories. In theories which admit a certain duality we model orientifold lines as orthosymplectic modules for the CoHA and describe the basic structure of these modules using moduli stacks of objects with classical type stabilizer groups.
