Flips of moduli of stable torsion free sheaves with $c_1=1$ on
$\\mathbb{P}^2$ (JAPANESE)
[ Abstract ]
We study flips of moduli schemes of stable torsion free sheaves
on the projective plane via wall-crossing phenomena of Bridgeland stability.
They are described as stratified Grassmann bundles by variation of
stability of modules over certain finite dimensional algebra.
