This quantity provides the complaints from the convention on low dimensional topology held on the collage of Madeira (Portugal). the development used to be attended by means of prime scientists within the box from the united states, Asia, and Europe.
The booklet has major elements. the 1st is dedicated to the Poincaré conjecture, characterizations of $PL$-manifolds, masking quadratic types of hyperlinks and to different types in low dimensional topology that seem in reference to conformal and quantum box thought. the second one a part of the amount covers topological quantum box thought and polynomial invariants for rational homology 3-spheres, derived from the quantum $SU(2)$-invariants linked to the 1st cohomology classification modulo , knot thought, and braid teams. This assortment displays improvement and growth within the box and provides fascinating and new effects.

Non-Riemannian Geometry bargains essentially with manifolds ruled by means of the geometry of paths co-developed via the celebrated mathematician Luther Pfahler Eisenhart, the writer of this article. He starts with a attention of uneven connections, after which proceeds to a contrasting survey of symmetric connections. Discusses projective geometry of paths and the geometry of sub-spaces. 1927 version.
