comment Limits of integration after change of variable in higher dimensions
Thanks for migrating my question to the math section and for the quick reply. Just another quick question since you are the expert. Is the derivative of the indicator function defined as the delta function? The reason I ask this is because in general I could have another function of $y$ accompanying the $\phi(a-y-\gamma)$ in the y-integral and in this case if the derivative can be defined then the y-integral could be performed by integration by parts. Am I right or am I missing something here?
