Query: On the Morse--Novikov Cohomology of blowing up complex manifolds   Inspired by the recent works of S. Rao--S. Yang--X.-D. Yang and L. Meng on
the blow-up formulae for de Rham and Morse--Novikov cohomology groups, we give
a new simple proof of the blow-up formula for Morse--Novikov cohomology by
introducing the relative Morse--Novikov cohomology group via sheaf cohomology
theory and presenting the explicit isomorphism therein.
