Metric SYZ conjecture and non-archimedean geometry [PDF]
arXiv, 2020 We show that assuming a conjecture in non-archimedean geometry, then a metric formulation of the SYZ conjecture can be proved in large generality.

Log‐Euclidean bag of words for human action recognition
IET Computer Vision, 2015 Representing videos by densely extracted local space–time features has recently become a popular approach for analysing actions. In this study, the authors tackle the problem of categorising human actions by devising bag of words (BoWs) models based on ...

Noncommutative spectral geometry of Riemannian foliations [PDF]
arXiv, 1997 We construct spectral triples in a sense of noncommutative differential geometry, associated with a Riemannian foliation on a compact manifold, and describe its dimension spectrum.

One-loop quantization of Euclidean D3-branes in holographic backgrounds
Journal of High Energy PhysicsIn this note we analyze the semi-classical quantization of D3-branes in three different holographic backgrounds in type IIB string theory. The first background is Euclidean AdS5 with S 1 × S 3 boundary accompanied with a twist to preserve supersymmetry ...
