|
Аннотация: In the last speech, we introduced basic definitions and theorems of secant-quandle as invariant of braids even knots. In this speech, we discuss more detail, according a specific example. Further more, we plan to generalize this invariant to secant-biquandle and virtual secant-quandle.
