Birational self-maps and piecewise algebraic geometry Lamy, Stéphane 92463 Sebag, Julien 92464 415 Let X be a smooth projective complex variety, of dimension 3, whose Hodge numbers h(3, 0)(X), h(1, 0)(X) both vanish. Let f : X ⇢ X be a birational map that induces an isomorphism U ≌ V on (dense) open subvarieties U, V of X. Then we show that the complex varieties (X \ U)(red), (X \ V)(red) are piecewise isomorphic. departmental bulletin paper Graduate School of Mathematical Sciences, The University of Tokyo 2012-10-22 application/pdf Journal of mathematical sciences, the University of Tokyo 3 19 325 357 AA11021653 13405705 https://repository.dl.itc.u-tokyo.ac.jp/record/40022/files/jms190305.pdf http://hdl.handle.net/2261/55430 https://repository.dl.itc.u-tokyo.ac.jp/records/40022 eng
