چکیده

Building upon the work of [Morelli1,2], we give a coherent presentation of Morelli’s algorithm for the weak and strong factorization of toric birational maps. We also discuss its toroidal extension, which plays a crucial role in the recent solutions [W lodarczyk2,3, Abramovich-Karu-Matsuki-W lodarczyk] of the weak factorization conjecture of general birational maps.

Erratum to the Paper “a Note on the Factorization Theorem of Toric Birational Maps after Morelli and Its Toroidal Extension”

1. the failure of the algorithm in [AMR] and [Morelli1] for the strong factorization pointed out by Kalle Karu, 2. the statement of a refined weak factorization theorem for toroidal birational morphisms in [AMR], in the form utilized in [AKMR] for the proof of the weak factorization theorem for general birationla maps, avoiding the use of the above mentioned algorithm for the strong factorizati...

Lectures on Factorization of Birational Maps

This is an expanded version of the notes for the lectures given by the author at RIMS in the summer of 1999 to provide a detailed account of the proof for the (weak) factorization theorem of birational maps by Abramovich-Karu-MatsukiW lodarczyk [1]. All the main ideas of these lecture notes, therefore, are derived from the collaboration and joint work with D. Abramovich, K. Karu and J. W lodarc...

Local Strong Factorization of Birational Maps

The strong factorization conjecture states that a proper birational map between smooth algebraic varieties over a field of characteristic zero can be factored as a sequence of smooth blowups followed by a sequence of smooth blowdowns. We prove a local version of the strong factorization conjecture for toric varieties. Combining this result with the monomialization theorem of S. D. Cutkosky, we ...

Birational Cobordisms and Factorization of Birational Maps

In this paper we develop a Morse-like theory in order to decompose birational maps and morphisms of smooth projective varieties defined over a field of characteristic zero into more elementary steps which are locallyétale isomorphic to equivariant flips, blow-ups and blow-downs of toric varieties (see Theorems 1, 2 and 3). The crucial role in the considerations is played by K *-actions where K ...

On Oda’s Strong Factorization Conjecture

The Oda’s Strong Factorization Conjecture states that a proper birational map between smooth toric varieties can be decomposed as a sequence of smooth toric blowups followed by a sequence of smooth toric blowdowns. This article describes an algorithm that conjecturally constructs such a decomposition. Several reductions and simplifications of the algorithm are presented and some special cases o...
