Minkowski Difference

minkowski_difference(X::LazySet, Y::LazySet)

Compute the Minkowski difference of two sets.

Input

• X – set
• Y – set

Output

A set representing the Minkowski difference $X ⊖ Y$.

Notes

The Minkowski difference of two sets $X$ and $Y$ is defined as

\[ X ⊖ Y = \{z \mid \{z\} ⊕ Y ⊆ X\}\]

The convenience alias pontryagin_difference is also available.

There is some inconsistency in the literature regarding the naming conventions. In this library, both Minkowski difference and Pontryagin difference refer to the geometric difference of two sets.
