概要
The concept of a $G$-family of quandles was
introduced by Ishii, Iwakiri, Jang and Oshiro in order to
study knotted trivalent graphs. Colorings of such graphs
extend to colorings of foams which locally look like
$Y$ times an interval. In this talk, I develop the notion
of foams and the notion of homology of $G$-families of
quandles that simultaneously generalizes group and
quandle homology.
