‣ InfoLocales | ( info class ) |
‣ UniqueMorphism( A, B ) | ( operation ) |
Returns: a CAP morphism

‣ IsThinCategory( C ) | ( property ) |
Returns: true or false
The property of C being a thin CAP category.
‣ IsDiscreteCategory( C ) | ( property ) |

‣ IsMonoidalProset( C ) | ( property ) |
Returns: true or false
The property of C being a monoidal thin category.
‣ IsClosedMonoidalProset( C ) | ( property ) |
Returns: true or false
The property of C being a closed monoidal thin category.
‣ IsCoclosedMonoidalProset( C ) | ( property ) |
Returns: true or false
The property of C being a coclosed monoidal thin category.
‣ IsSymmetricMonoidalProset( C ) | ( property ) |
Returns: true or false
The property of C being a symmetric monoidal thin category.
‣ IsSymmetricClosedMonoidalProset( C ) | ( property ) |
Returns: true or false
The property of C being a symmetric closed monoidal thin category.
‣ IsSymmetricCoclosedMonoidalProset( C ) | ( property ) |
Returns: true or false
The property of C being a symmetric coclosed monoidal thin category.
‣ 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.
‣ IsCategoryWithoutMorphismData( object ) | ( filter ) |
Returns: true or false
The GAP category of categories with morphisms without a morphism datum.
‣ 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.
‣ AddAreIsomorphicForObjectsIfIsHomSetInhabited( C, F ) | ( operation ) |
‣ AddAreIsomorphicForObjectsIfIsHomSetInhabited( C, F, weight ) | ( 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. Optionally, a weight (default: 100) can be specified which should roughly correspond to the computational complexity of the function (lower weight = less complex = faster execution). F: ( arg2, arg3 ) \mapsto \mathtt{AreIsomorphicForObjectsIfIsHomSetInhabited}(arg2, arg3).
‣ AddUniqueMorphism( C, F ) | ( operation ) |
‣ AddUniqueMorphism( C, F, weight ) | ( 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. Optionally, a weight (default: 100) can be specified which should roughly correspond to the computational complexity of the function (lower weight = less complex = faster execution). F: ( A, B ) \mapsto \mathtt{UniqueMorphism}(A, B).
Prosets are thin categories, i.e., each Hom-set is either a singleton or empty.
