An Alzheimer’s disease category progression sub-grouping analysis using manifold learning on ADNI
Many current statistical and machine learning methods have been used to explore Alzheimer’s disease (AD) and its associated patterns that contribute to the disease.

Asymptotically conical Calabi-Yau manifolds, III [PDF]
This is the first part in a two-part series on complete Calabi-Yau manifolds asymptotic to Riemannian cones at infinity. We begin by proving general existence and uniqueness results.

Dubrovin's duality for F-manifolds with eventual identities [PDF]
A vector field <i>E</i> on an <i>F</i>-manifold (M, o, e) is an eventual identity if it is invertible and the multiplication X*Y := X o Y o E^{-1} defines a new F-manifold structure on <i>M</i>.

Bucshbaum simplicial posets [PDF]
The family of Buchsbaum simplicial posets generalizes the family of simplicial cell manifolds. The $h'-$vector of a simplicial complex or simplicial poset encodes the combinatorial and topological data of its face numbers and the reduced Betti numbers of

Contact Semi-Riemannian Structures in CR Geometry: Some Aspects
There is one-to-one correspondence between contact semi-Riemannian structures ( η , ξ , φ , g ) and non-degenerate almost CR structures ( H , ϑ , J ) .

Quasi-Kahler Chern-flat manifolds and complex 2-step nilpotent Lie algebras [PDF]
The study of quasi-Kaehler Chern-flat almost Hermitian manifolds is strictly related to the study of anti-bi-invariant almost complex Lie algebras.

Topological field theories induced by twisted R-Poisson structure in any dimension
We construct a class of topological field theories with Wess-Zumino term in spacetime dimensions ≥ 2 whose target space has a geometrical structure that suitably generalizes Poisson or twisted Poisson manifolds.

Finiteness of classifying spaces of relative diffeomorphism groups of 3–manifolds [PDF]
The main theorem shows that if M is an irreducible compact connected ori- entable 3{manifold with non-empty boundary, then the classifying space BDi (M rel @M) of the space of dieomorphisms of M which restrict to the identity map on @M has the homotopy ...
