Rational map

Classify landscape ecology system and establish maps of landscape ecology in Son La province; clarify the changes of landscape ecology in Son La over time (from 2005 to 2015); identify the scientific foundations based on studing landscape ecology to orientate rational territory use in agriculture, forestry and conservation

In the article, we see that the birational maps of degree d of the projective space Pn k form a locally closed subvariety of the projective space P(Sdn11), denoted Crd(n). In this paper, we will construct the notion of extended degree of rational maps, then we obtain the functor crd(n) that represents the variety Crd(n).

A natural and simple question asked is: Does the Cremona group Cr(n) admit a structure that is of an algebraic group of infinite dimension. This is still an open question because we don’t know if the set Cr≤d(n) of birational maps of degree ≤ d admits a structure of the algebraic variety.

The thesis aims to: Classify landscape ecology system and establish maps of landscape ecology in Son La province. Clarify the changes of landscape ecology in Son La over time (from 2005 to 2015). Identify the scientific foundations based on studing landscape ecology to orientate rational territory use in agriculture, forestry and conservation.

Let X be a projective manifold and f : X → X a rational mapping with large topological degree, dt λk−1 (f ) := the (k − 1)th dynamical degree of f . We give an elementary construction of a probability measure µf such that d−n (f n )∗ Θ → µf for every smooth probability measure Θ on X. We show t that every quasiplurisubharmonic function is µf -integrable. In particular µf does not charge either points of indeterminacy or pluripolar sets, hence µf is f -invariant with constant jacobian f ∗ µf = dt µf...
