Sphere geometry and invariants
A finite abstract simplicial complex G defines two finite simple graphs: the Barycentric refinement G1, connecting two simplices if one is a subset of the other and the connection graph G′, connecting two simplices if they intersect. We prove that the Poincaré-Hopf value i(x) = 1−χ(S(x)), where χ(S(x)) is the Euler characteristics of the unit sphere S(x) of a vertex x in G1, agrees with the Gre...
متن کاملThe Symplectic Camel and Quantum Universal Invariants: the Angel of Geometry versus the Demon of Algebra
A positive de nite symmetric matrix quali es as a quantum mechanical covariance matrix if and only if + 12 i~ 0 where is the standard symplectic matrix. This well-known condition is a strong version of the uncertainty principle, which can be reinterpreted in terms of the topological notion of symplectic capacity, closely related to Gromovs non-squeezing theorem. We show that a recent re nement...
متن کاملBottom tangles and universal invariants
A bottom tangle is a tangle in a cube consisting only of arc components, each of which has the two endpoints on the bottom line of the cube, placed next to each other. We introduce a subcategory B of the category of framed, oriented tangles, which acts on the set of bottom tangles. We give a finite set of generators of B , which provides an especially convenient way to generate all the bottom t...
متن کاملTail Recursion Through Universal Invariants
Tail recursive constructions suggest a new semantics for datatypes, which allows a direct match between speciications and tail recursive programs. The semantics focusses on loops, their xpoints, invariants and convergence. Convergent models of the natural numbers and lists are examined in detail, and, under very mild conditions, are shown to be equivalent to the corresponding initial algebra mo...
متن کاملEnumerative geometry and knot invariants
We review the string/gauge theory duality relating Chern-Simons theory and topological strings on noncompact Calabi-Yau manifolds, as well as its mathematical implications for knot invariants and enumerative geometry.
