Toric schemes over a discrete valuation ring and tropical compactifications

Qu, Zhenhua, 1981- 21 March 2011 (has links)
Let Y be a subvariety of an algebraic torus, Tevelv (24) defined and studied tropical compactifications as certain nice compactifications of Y. We give a criterion for certain compactification to be a schön compactification, and as a corollary, we show that any variety contains an open very affine schön variety. Using toric schemes defined over a discrete valuation ring, we generalize the theory of tropical compactification to the nonconstant coefficient case, i.e. for varieties defined over a discrete valuation ring. / text
