I see a term like$$\int_0^{t''} \left[ \int_{t'}^t \omega(t'') \omega(t') dt' \right] dt''$$here ##\omega## is a matrix. How to interpret this integral - the integration variables are in the limits, in places where they don't make sense. Is that a mistake? It's given that the range of integration is ##0 < t' < t'' < t##, i.e. a triangle in the ##t'##-##t''## plane. Reference is top of page 50 here. Thanks!
