Directed semirings

Description

A "directed semiring" refers to the semiring composed of the union of upwards directed sets as multiplication, and intersection of downwards directed sets as addition.

Synopsis

newtype Directed = Directed {
- getDirected :: Ordering
}

Directed semirings

newtype Directed Source #

Wrapper for the semiring of upwards and downwards directed sets.

For the individual join/meet monoids associated with either algebra, see Max Ordering, and Min Ordering@.
