Query: Morse theory on manifolds with boundary I. Strong Morse function,
  cellular structures and algebraic simplification of cellular differential   Main subject of the paper is a (strong) Morse function on a compact manifold
with boundary. We construct a cellular structure and discuss its algebraic
properties in this paper. Also we get an estimation on Arnold's question on a
number of critical points of a Morse function with given boundary condition.
