I understand that $\land$ denotes a conjunction, but what does this mean when applied to stochastic processes? I have come across part of my Stochastic Calculus notes that features reference to the process:
$$X(t \land \tau_n)_{t \in \left[0, T\right]}$$
where $\tau_n$ is the $n$th in a sequence of stopping times. Does this mean that the process $X$ can only take as input values such that $t = \tau_n$?
It's the min function. So $a \wedge b = \text{min}(a,b)$.
