2 Posets (partially ordered sets)

2.1 Properties

2.1-1 IsPosetCategory
‣ IsPosetCategory( C )( property )

Returns: true or false

The property of C being a poset (category).

2.1-2 IsTotalOrderCategory
‣ IsTotalOrderCategory( C )( property )

Returns: true or false

The property of C being a total order CAP category.

2.1-3 IsMonoidalPoset
‣ IsMonoidalPoset( C )( property )

Returns: true or false

The property of C being a monoidal thin skeletal category.

2.1-4 IsClosedMonoidalPoset
‣ IsClosedMonoidalPoset( C )( property )

Returns: true or false

The property of C being a closed monoidal thin skeletal category.

2.1-5 IsCoclosedMonoidalPoset
‣ IsCoclosedMonoidalPoset( C )( property )

Returns: true or false

The property of C being a coclosed monoidal thin skeletal category.

2.1-6 IsSymmetricMonoidalPoset
‣ IsSymmetricMonoidalPoset( C )( property )

Returns: true or false

The property of C being a symmetric monoidal thin skeletal category.

2.1-7 IsSymmetricClosedMonoidalPoset
‣ IsSymmetricClosedMonoidalPoset( C )( property )

Returns: true or false

The property of C being a symmetric closed monoidal thin skeletal category.

2.1-8 IsSymmetricCoclosedMonoidalPoset
‣ IsSymmetricCoclosedMonoidalPoset( C )( property )

Returns: true or false

The property of C being a symmetric coclosed monoidal thin skeletal category.

2.2 Operations

2.2-1 IsEqualForObjectsIfIsHomSetInhabited
‣ IsEqualForObjectsIfIsHomSetInhabited( A, B )( operation )

Returns: true or false

Check if A is equal 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 partial order.

2.3 Add-methods

2.3-1 AddIsEqualForObjectsIfIsHomSetInhabited
‣ AddIsEqualForObjectsIfIsHomSetInhabited( 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 IsEqualForObjectsIfIsHomSetInhabited. \(F: ( arg2, arg3 ) \mapsto \mathtt{IsEqualForObjectsIfIsHomSetInhabited}(arg2, arg3)\).

Posets are skeletal, thin categories.
