چکیده
We prove that many of the results log minimal model program hold for threefolds over fields characteristic p > 5 $p>5$ which are not necessarily perfect. This includes existence flips, cone theorem, contraction theorem birational extremal rays and models. As well as pertaining to geometry fibrations relative dimension 3 algebraically closed fields, they have applications tight closure in 4.

متن کاملReal Algebraic Threefolds Ii. Minimal Model Program
In real algebraic geometry, one of the main directions of investigation is the topological study of the set of real solutions of algebraic equations. The first general result was proved in [Nash52], and later developed by many others (see [Akbulut-King92] for some recent directions). One of these theorems says that every compact differentiable manifold can be realized as the set of real points ...

Let $K$ be a field of characteristic$p>0$, $K[[x]]$, the ring of formal power series over $ K$,$K((x))$, the quotient field of $ K[[x]]$, and $ K(x)$ the fieldof rational functions over $K$. We shall give somecharacterizations of an algebraic function $fin K((x))$ over $K$.Let $L$ be a field of characteristic zero. The power series $finL[[x]]$ is called differentially algebraic, if it satisfies...
