The Equalizer Conjecture For The Free Group of Rank Two
نویسندگان
چکیده
Abstract The equalizer of a set homomorphisms $S: F(a, b)\rightarrow F(\Delta)$ has rank at most two if S contains an injective map and is not finitely generated otherwise. This proves strong form Stallings’ Equalizer Conjecture for the free group two. Results are also obtained pairs $g, h:F(\Sigma)\rightarrow when images inert in, or retracts of, $F(\Delta)$.

15 صفحه اولThe Auslander-Reiten Conjecture for Group Rings
This paper studies the vanishing of $Ext$ modules over group rings. Let $R$ be a commutative noetherian ring and $ga$ a group. We provide a criterion under which the vanishing of self extensions of a finitely generated $Rga$-module $M$ forces it to be projective. Using this result, it is shown that $Rga$ satisfies the Auslander-Reiten conjecture, whenever $R$ has finite global dimension and $ga...
