The kernel in geometry is the set of all points a such that for all points b inside a polygon P, the segment ab lies entirely within P.[1]
In abstract algebra, the kernel of a function between two groups is the set of all members of the first which map to the identity of the second. Similarly, the kernel of a mapping in linear algebra from one vector space to another is the set of vectors mapped to the zero vector.
