morphisms between bound quivers


Let (Q,I) and (Q,I) be bound quivers (http://planetmath.org/AdmissibleIdealsBoundQuiverAndItsAlgebra) over the same base fieldMathworldPlanetmath k.

Definition. A morphism F:QQ is said to be bounded by (I,I) if the induced linear map (http://planetmath.org/MorphismsOfPathAlgebrasInducedFromMorphismsOfQuivers) F¯:kQkQ is such that

F¯(I)I.

In this case we write

F:(Q,I)(Q,I)

and we say that F is a morphism of bound quivers.

If F:(Q,I)(Q,I) is a morphism of bound quivers, then F¯:kQkQ induces a linear map

F¯¯:kQ/IkQ/I.

Furthermore, if F0 is injective, then F¯ is a homomorphismPlanetmathPlanetmathPlanetmathPlanetmathPlanetmath of algebras (see this entry (http://planetmath.org/MorphismsOfPathAlgebrasInducedFromMorphismsOfQuivers) for details) and thus F¯¯ is a homormorphism of algebras.
