Eigenvalue varieties of abelian trees of groups and link-manifolds

This result is studied there to get a lower bound for the number of nested limit cycles of a polynomial system of degree n ∈ {2`, 2` + 1}.. The gap between these two results remains

Here we similarly define an abelian 2-group D der ∗ W which models the 1-type of the K-theory spectrum K(DW) of the right 2 pointed derivator DW associated to a Waldhausen category

The aim of this paper is to study groups G = AB which are factor- ized as the product of π-decomposable subgroups A and B, for a set of primes π.. Moreover, we always use X π to

In the first case, it is shown that the characters of the free and the free abelian topological groups on X are both equal to the “small cardinal” d if X is compact and metrizable,

The usual way to investigate the statistical properties of finitely generated subgroups of free groups, and of finite presentations of groups, is based on the so-called

Theorem 1.1 implies the following result from [5]: every Polish abelian group is the quotient of a closed abelian subgroup of the unitary group of a separable Hilbert space

Also we define the composition of binary trees as a commutative binary operation, *, such that for binary trees A and B, A ∗ B is the binary tree obtained by attaching a copy of B

The proof is based on Theorem 2.1 giving conditions under which a meager semitopological group is left (right) meager and Theorem 3.2 describing some oscillator properties
