متن کاملThe Kirby Torus Trick for Surfaces
In the late 1960s the breakthrough that led to the Kirby–Siebenmann classification of PL structures on high-dimensional topological manifolds was the Kirby torus trick [K]. A few years later it was shown in a paper by A.J.S.Hamilton [H] that the torus trick could also be applied in dimension 3 to give new proofs of the earlier results of Bing and Moise on the existence and uniqueness of triangu...
متن کاملKirby Elements and Quantum Invariants
We define the notion of a Kirby element of a ribbon category C (not necessarily semisimple). Kirby elements lead to 3-manifolds invariants. We characterize a set of Kirby elements (in terms of the structural morphisms of a Hopf algebra in C) which is sufficiently large to recover the quantum invariants of 3-manifolds of Reshetikhin-Turaev, of Hennings-Kauffman-Radford, and of Lyubashenko. The c...
متن کاملDescription of the final instar larva of Rhionaeschna vigintipunctata (Ris, 1918) (Odonata: Aeshnidae).

The description is based on a series of mature female larvae collected in Tucumán (NW Argentina) and reared to imago.
