The $SL (2, C)$ -character variety of an arborescent knot

Haimiao Chen

We describe a procedure for computing the $SL (2, C)$ -character variety of an arborescent knot. Along the way, we clarify several facts about representations of arbore…

On skein algebras of planar surfaces

Haimiao Chen

Let $R$ be a commutative ring with identity and a fixed invertible element $q^{\frac{1}{2}}$ . Let $S_{n}$ denote the Kauffman bracket skein algebra of the $n$ -holed disk $Î…

Finite $p$ -groups of class $2$ as central extensions

Haimiao Chen

Finite $p$ -groups of nilpotency class 2 are treated from the perspective of central extensions. Given finite abelian groups $G, A$ , we derive an explicit formula for cocycles repres…
