概要
Kauffman introduced the notion of a virtual knot, which is
a generalization of a classical knot.
In this talk, we introduce a generalization of a surface knot,
which is called a virtual surface knot.
We will also give an invariant of a virtual surface knot
and a non-trivial virtual surface knot which is not a classical surface
knot by using a mirror image.
