On the Indecomposable Representations of a Certain Class of Groups
1. Introduction LET 0 be a finite group. If p is a prime which, divides the order of G, there exists in general an infinite number of indecomposable representations of 0 over a field of characteristic p. We are concerned here with the in-decomposable representations of a group G which is an extension of a 2?-nilpotent"f group by a cyclic group of order prime to p. We reduce the study of these r...
متن کاملDeformation of Outer Representations of Galois Group
To a hyperbolic smooth curve defined over a number-field one naturally associates an "anabelian" representation of the absolute Galois group of the base field landing in outer automorphism group of the algebraic fundamental group. In this paper, we introduce several deformation problems for Lie-algebra versions of the above representation and show that, this way we get a richer structure than t...
متن کاملIndecomposable Representations and the Loop-space Operation1
For a certain class of algebras, including group-algebras of finite groups, we shall introduce a permutation in the set of isomorphismclasses of nonprojective indecomposable modules. This permutation is in essence given by the loop-space functor [2]. It is to be hoped that the study of this permutation may give some insight into the difficult problem of classifying indecomposable representation...
متن کاملComment on "Gravity and the Poincaré group"
Following the approach of Grignani and Nardelli [1], we show how to cast the two–dimensional model L ∼ curv + torsion + cosm.const — and in fact any theory of gravity — into the form of a Poincaré gauge theory. By means of the above example we then clarify the limitations of this approach: The diffeomorphism invariance of the action still leads to a nasty constraint algebra. Moreover, by simple...
متن کاملIndecomposable Representations of Semisimple Lie Groups
Let G be a semisimple connected linear Lie group, w, a finite-dimensional irreducible representation of G, tr2 an infinite-dimensional irreducible representation of G which has a nontrivial extension with w,. We study the category of all Harish-Chandra modules whose composition factors are equivalent to w, and Introduction. In a series of articles [5]-[8], I. M. Gelfand, Graev and Ponomarev cla...
