For the handlebody Hg of genus g, Przytycki studied the (Kauffman bracket) skein module 𝒮q(Hn#Hm) of the connected sum Hn#Hm at q. One of his results is that, in the case when 1 qk is invertible for any k0, a homomorphism φ:𝒮q(Hn Hm) 𝒮q(Hn#Hm) is an isomorphism, which is induced by a natural way. In this paper, in the case when n = m = 1, the ground ring is , and q is a 4k-th root of unity (k 2), we show that φ is not injective.

Kauffman 支架绞纱模块的连接总和和非注入性

用于把手HGG, Przytycki 研究了(考夫曼支架)绞纱模块𝒮q(Hn#H)连接总和的Hn#Hq. 他的结果之一是,在这种情况下,1 - qķ是可逆的任何ķ0, 同态φ𝒮q(Hn H) 𝒮q(Hn#H)是同构,由自然方式诱导而来。在本文中,当n = = 1,接地环为, 和q 是一个4ķ- 统一的根 (ķ 2),我们证明了φ不是单射的。
