3.2 The standard planar algebras of tangles and of chord diagrams and the no-go theorem

Summary. Here we will describe the standard planar algebras of tangles and its associated standard algebra of chord diagrams, and show that there is essential planar algebra map from the former planar algebra to the latter. For now, see [BN9, slide 16].
