32 p, 419.6 KB Strong inner inverses in endomorphism rings of vector spaces / Bergman, George M. (University of California)
For V a vector space over a field, or more generally, over a division ring, it is well-known that every x ∈ End(V ) has an inner inverse; that is, that there exists y ∈ End(V ) satisfying xyx = x. [...]

31 p, 418.1 KB Minimal faithful modules over Artinian rings / Bergman, George M. (University of California)
Let R be a left Artinian ring, and M a faithful left R-module such that no proper submodule or homomorphic image of M is faithful. If R is local, and socle(R) is central in R, we show that length(M=J(R)M) + length(socle(M)) ≤ length(socle(R)) + 1. [...]

36 p, 471.6 KB An inner automorphism is only an inner automorphism, but an inner endomorphism can be something strange / Bergman, George M.
The inner automorphisms of a group G can be characterized within the category of groups without reference to group elements: they are precisely those au-tomorphisms of G that can be extended, in a functorial manner, to all groups H given with homomorphisms G ! H: (Precise statement in x1. [...]
