چکیده

Let R denote a 2-fir. The notions of F -independence and algebraic subsets of R are defined. The decomposition of an algebraic subset into similarity classes gives a simple way of translating the F -independence in terms of dimension of some vector spaces. In particular to each element a ∈ R is attached a certain algebraic set of atoms and the above decomposition gives a lower bound of the length of the atomic decompositions of a in terms of dimensions of certain vector spaces. A notion of rank is introduced and fully reducible elements are studied in details.

We prove that any nonconstant entire holomorphic curve f : C → X in a projective algebraic hypersurface X ⊂ P(C) of arbitrary dimension n > 2 must be algebraically degenerate if X is generic and if its degree satisfies the effective lower bound degX > n n+5 . Table of contents

The classical Cayley map, X → (In − X)(In + X) −1 , is a birational iso-morphism between the special orthogonal group SOn and its Lie algebra son, which is SOn-equivariant with respect to the conjugating and adjoint actions respectively. We ask whether or not maps with these properties can be constructed for other algebraic groups. We show that the answer is usually " no " , with a few exceptio...

We present a sufficient condition for groups to satisfy the FarrellJones Conjecture in algebraic K-theory and L-theory. The condition is formulated in terms of finite quotients of the group in question and is motivated by work of Farrell-Hsiang. This version is different from the published version. A number of typos and an incorrect formula for the transfer before Lemma 6.3 pointed out by Holge...

We show that for every generic smooth projective hypersurface X ⊂ P, n > 2, there exists a proper algebraic subvariety Y $ X such that every nonconstant entire holomorphic curve f : C → X has image f(C) which lies in Y , provided degX > n n+5 . Table of contents

For an effective divisor on a smooth algebraic variety or a complex manifold, we show that the associated multiplier ideals coincide essentially with the filtration induced by the filtration V constructed by B. Malgrange and M. Kashiwara. This implies another proof of a theorem of L. Ein, R. Lazarsfeld, K.E. Smith and D. Varolin that any jumping coefficient in the interval (0,1] is a root of th...
