Query: Nonlinear differential equations arising from Boole numbers and their
  applications   In this paper, we study nonlinear differential equations satisfied by the
generating function of Boole numbers. In addition, we derive some explicit and
new interesting identities involving Boole numbers and higher-order numbers
arising from our nonlinear differential equations.
