| Research Abstract |
In this research, we gave the following results: (1) We gave an evaluation for the minimum number of colors for surface-knots. (2) We defined a G-family of quandles, and constructed an invariant for handlebody-knots. (3) We researched about the colorability with linear Alexander quandles. (4) We showed that rack colorings are invariant for 2-knots.
