Abstract

Let \Field\Field be an algebraically closed field. For nNn \in \mathbb{N} and δ,δL,δR,κL,κR,κ\Field\delta, \delta_L, \delta_R, \kappa_L, \kappa_R, \kappa \in \Field, the symplectic blob algebra \sba(δ,δL,δR,κL,κR,κ)\sba(\delta, \delta_L, \delta_R, \kappa_L, \kappa_R, \kappa) is a finite dimensional non-commutative \Field\Field-algebra that may be viewed as an extension of the Temperley-Lieb algebra. In a previous paper, we defined, for any nNn \in \mathbb{N}, a tensor space module \tensor[\sba]V(n)\tensor[_\sba]{\mathcal{V}(n)}{}. In this paper we generalise an argument used by Martin and Ryom-Hansen in their study of the (ordinary) blob algebra to show that when \sba\sba is quasihereditary the module \tensor[\sba]V(n)\tensor[_\sba]{\mathcal{V}(n)}{} is full-tilting.
