Query: Limiting weak-type behaviors of some integral operators   In this paper, we explore the limiting weak-type behaviors of some integral
operators including maximal operators, singular and fractional integral
operators and maximal truncated singular integrals et al. Some optimal limiting
weak-type behaviors are given, which essentially improve and extend the
previous results in this topics.
