t-conorm (pluralt-conorms)

1. (fuzzy logic) A binary function from [0,1] × [0,1] to [0,1], which, when given (a,b) as input, returns one minus at-norm of (1 −a, 1 −b).

   Thet-conorm${\displaystyle \sqrt{x^2+y^2-x^2{y}^2}}$ is dominated by thet-conorm${\displaystyle x+y-xy}$, which is in turn dominated by thet-conorm${\displaystyle \frac{x+y}{1+xy}}$.

   At-conorm acts as a disjunction in fuzzy logic or as a union in fuzzy set theory. When one of its arguments is 0, it returns its other argument; when one of its arguments is 1, it returns 1. It is both associative and commutative, and its partial derivatives with respect to its parameters are non-negative.
