Closed Formulas for $\hat{I}\cdot$-Corrections in the Once Punctured Torus

Nelson A. Colon Vargas

We study $\hat{I}\cdot$-correction terms in the Kauffman bracket skein algebra of the once-punctured torus $K_t(\hat{I}{\pounds }_{1,1})$. While the Frohman--Gelca product-to-sum rule gives an explicit mul…
