數學特別是序理論中,完全海廷代數是作為完全海廷代數。完全海廷代數是三個不同範疇對象,它們是範疇CHey,locales的範疇Loc,它的對偶frames的範疇Frm

定義

考慮是完全格偏序集合P, ≤)。則P是完全海廷代數,如果任何下列等價條件中的一個成立:

  • P是海廷代數,就是說運算 ( x - )有一個右伴隨(也叫做(單調)伽羅瓦連接的下伴隨),對於每個P的元素x
  • 對於所有P的元素x和所有P的子集S,下列無限分配律成立:
  • P是分配格,就是說對於所有P中的x, yz,有著
並且P是交連續性的,就是說交運算 ( x - )對於所有P中的x斯科特連續性的。

Surprisingly extensive resource on locales and Heyting algebras. Takes a more categorical viewpoint.
