‣ InfoLocales | ( info class ) |
‣ UniqueMorphism( A, B ) | ( operation ) |
Returns: a CAP morphism
Construct the unique morphism with source A and target B.
‣ AreIsomorphicForObjectsIfIsHomSetInhabited( A, B ) | ( operation ) |
Returns: true or false
Check if A is isomorphic to B under the assumption that there exists a morphism from A to B, i.e., if A is known to be less or equal to B w.r.t. the preorder.
‣ AddAreIsomorphicForObjectsIfIsHomSetInhabited( C, F ) | ( operation ) |
Returns: nothing
The arguments are a category \(C\) and a function \(F\). This operation adds the given function \(F\) to the category for the basic operation AreIsomorphicForObjectsIfIsHomSetInhabited. \(F: ( arg2, arg3 ) \mapsto \mathtt{AreIsomorphicForObjectsIfIsHomSetInhabited}(arg2, arg3)\).
‣ AddUniqueMorphism( C, F ) | ( operation ) |
Returns: nothing
The arguments are a category \(C\) and a function \(F\). This operation adds the given function \(F\) to the category for the basic operation UniqueMorphism. \(F: ( arg2, arg3 ) \mapsto \mathtt{UniqueMorphism}(arg2, arg3)\).
‣ IsObjectInThinCategory( object ) | ( filter ) |
Returns: true or false
The GAP category of objects in a thin CAP category.
‣ IsMorphismInThinCategory( morphism ) | ( filter ) |
Returns: true or false
The GAP category of morphisms in a thin CAP category.
Prosets are thin categories, i.e., each Hom-set is either a singleton or empty.
‣ IsThinCategory( C ) | ( property ) |
Returns: true or false
The property of C being a thin CAP category.
