Some linear algebra

We show that every smooth toric variety (and many other algebraic spaces as well) can be realized as a moduli space for smooth, projective, polarized varieties. Some of these are not quasi-projective. This contradicts a recent paper (Quasi-projectivity of moduli spaces of polarized varieties, Ann. of Math. 159 (2004) 597–639.). A polarized variety is a pair (X, H) consisting of a smooth projective variety X and a linear equivalence class of ample divisors H on X. For simplicity, we look at the case when X is smooth, numerical and linear equivalence coincide for divisors on X, H is very...

The purpose of this section is to get a geometric understanding of linear estimation . First. we outline how projections are computed in linear algebra for finite dimensional vectors . Functional analysis generalizes this procedure to some infinite-dimensional spaces (so-called Hilbert spaces). and finally. we point out that linear estimation is a special case of an infinite-dimensional space
