A modification of the Hodge star operator on manifolds with boundary
Ryszard L. Rubinsztein
If M is a smooth compact oriented Riemannian manifold of dimension n=4k+2, with or without boundary, and F is a vector bundle on M with an inner product and a flat connection, we c…
The degree of an eight-dimensional real quadratic division algebra is 1, 3, or 5
Ernst Dieterich, Ryszard Rubinsztein
A celebrated theorem of Hopf, Bott, Milnor, and Kervaire states that every finite-dimensional real division algebra has dimension 1, 2, 4, or 8. While the real division algebras of…
Symplectic topology of SU(2)-representation varieties and link homology, I: Symplectic braid action and the first Chern class
Magnus Jacobsson, Ryszard L. Rubinsztein
There are some similarities between cohomology of SU(2)-representation varieties of the fundamental group of some link complements and the Khovanov homology of the links. We start…
Topological Quandles and Invariants of Links
Ryszard L. Rubinsztein
We introduce a notion of topological quandle. Given a topological quandle we associate to every classical link in an invariant which is a topological space…
