The … See more In the study of stochastic processes in mathematics, a hitting time (or first hit time) is the first time at which a given process "hits" a given subset of the state space. Exit times and return times are also examples of hitting … See more • Stopping time See more Let T be an ordered index set such as the natural numbers, $${\displaystyle \mathbb {N} ,}$$ the non-negative real numbers, [0, +∞), or a subset of these; elements See more • Any stopping time is a hitting time for a properly chosen process and target set. This follows from the converse of the Début theorem (Fischer, 2013). • Let B denote standard See more

In measure theory, projection maps often appear when working with product spaces: The product sigma-algebra of measurable spaces is defined to be the finest such that the projection mappings will be measurable. Sometimes for some reasons product spaces are equipped with sigma-algebra different than the product sigma-algebra.
