- However, even over the ring of integers, the module of rational numbers has an endomorphism ring that is a division ring, specifically the field of rational numbers.
- It is not only an abelian group but is also a ring with multiplication given by function composition; it is called the endomorphism ring of " M ".
- However, this is a stricter notion, since the endomorphism ring of a countably infinite dimensional vector space is semiprimitive, but not a subdirect product of simple rings,.
- More generally, square roots can be considered in any context in which a notion of " squaring " of some mathematical objects is defined ( including algebras of matrices, endomorphism rings, etc .)
- The possible types of endomorphism ring have been classified, as rings with lattice ? in "'C " "'d ", one must take into account the Riemann relations of abelian variety theory.
- The endomorphism ring of this is an order in a quaternion algebra over the rationals, and should act on the first cohomology group, which should be a 2-dimensional vector space over the coefficient field by analogy with the case of a complex elliptic curve.
- 20 ) " The endomorphism ring of an Abelian group is trivial if and only if the Abelian group in question is the trivial group . " Explanation / reference ? ( It's easy : there is always the identity endomorphism and the zero endomorphism .)
- It is known that the endomorphism ring End R ( " M " ) is a semilocal ring which is very close to a local ring in the sense that End R ( " M " ) has at most two maximal right ideals.
- There are " three types " of irreducible real representations of a finite group on a real vector space " V ", as the endomorphism ring commuting with the group action can be isomorphic to either the real numbers, or the complex numbers, or the quaternions.
- If A | B is in addition to being depth two a Frobenius algebra extension, the right and left endomorphism rings are anti-isomorphic, which restricts to an antipode on the bialgebroid \ mbox { End } \, { } _ BA _ B satisfying axioms of a Hopf algebroid.
- If an abelian group has a finite endomorphism ring, then it is necessarily a torsion abelian group . ( Otherwise multiplication by an integer gives an obvious injection from the set of integers into the endomorphism ring . ) In fact, for the same reason, the elements must have bounded order.
- If an abelian group has a finite endomorphism ring, then it is necessarily a torsion abelian group . ( Otherwise multiplication by an integer gives an obvious injection from the set of integers into the endomorphism ring . ) In fact, for the same reason, the elements must have bounded order.
- Even for group rings, there are examples when the characteristic of the field divides the order of the group : the Jacobson radical of the projective cover of the one-dimensional representation of the alternating group on five points over the field with three elements has the field with three elements as its endomorphism ring.
- The Hopf algebroid structure on the endomorphism ring S of the B-bimodule A ( discussed above ) becomes a Hopf algebra in the presence of the hypothesis that the centralizer R = \ { r \ in A : \ forall b \ in B, br = rb \ } is one-dimensional.
- The action of the Clifford algebra on ? is defined first by giving the action of an element of " V " on ?, and then showing that this action respects the Clifford relation and so extends to a homomorphism of the full Clifford algebra into the endomorphism ring End ( ? ) by the universal property of Clifford algebras.
- Given a right " R "-module U, the set of all " R "-linear maps from " U " to itself forms a ring with addition that is of function and multiplication that is of composition of functions; it is called the endomorphism ring of " U " and is denoted by \ operatorname { End } _ R ( U ).
- Conversely, any depth two extension A | B has a Galois theory based on the natural action of \ mbox { End } \, { } _ BA _ B on A : denoting this endomorphism ring by S, one shows S is a left bialgebroid over the centralizer R ( those a in A commuting with all b in B ) with a Galois theory similar to that of Hopf-Galois theory.
- There is a right bialgebroid structure on the B-centralized elements T in A \ otimes _ B A dual over R to S; certain endomorphism rings decompose as smash product, such as \ mbox { End } \, A _ B \ cong A \ otimes _ R S, i . e . isomorphic as rings to the smash product of the bialgebroid S ( or its dual ) with the ring A it acts on.
- By looking at the endomorphism ring of a module, one can tell whether the module is indecomposable : if and only if the endomorphism ring does not contain an idempotent element different from 0 and 1 . ( If " f " is such an idempotent endomorphism of " M ", then " M " is the direct sum of ker ( " f " ) and im ( " f " ) .)
