Derived Algebraic Geometry II: Noncommutative Algebra [article]

Jacob Lurie
2007 arXiv   pre-print
(ii) For every vertex k of K, the image of {k} ⊲ under f is a p-coCartesian morphism of X. (iii) There exists a vertex k of K such that the image of {k} ⊲ under f is a p-coCartesian morphism of X.  ...  More informally, a functor f : N(J 0 ) → C ⊗ belongs to E 0 (C) if there exists an object C = f ( 1 * ) ∈ C, such that for all n ≥ 0, the object f ( n * ) ∈ C ⊗ n * corresponds to (C, C, . . . , C) under  ...  Assertion (i) follows immediately from the stability of C under finite coproducts. We now prove (ii). Suppose given a pair of maps f : X → N and g : Y → N , respectively.  ...

Rho–tau embedding and gauge freedom in information geometry

Jan Naudts, Jun Zhang
2018 Information Geometry  
The standard model of information geometry, expressed as Fisher-Rao metric and Amari-Chensov tensor, reflects an embedding of probability density by log-transform.  ...  The present paper studies parametrized statistical models and the induced geometry using arbitrary embedding functions, comparing single-function approaches (Eguchi's U-embedding and Naudts' deformed-log  ...  Acknowledgements The project is supported in part by DARPA/ARO Grant W911NF-16-1-0383 ("Information Geometry: Geometrization of Science of Information", PI: Zhang).  ...

Lagrangian matching invariants for fibred four-manifolds: II

Tim Perutz
2008 Geometry and Topology  
Step (iv) Our task is now to compare the information found in steps (ii) and (iii). Suppose that k is odd.  ...  In Part II we continue where we left off. We begin, in Section 2, by restating Theorem B, or rather, stating a corollary of it which is our jumping-off point for this part.  ...

Quantitative symplectic geometry [article]

K.Cieliebak, H.Hofer, J.Latschev, F.Schlenk
2005 arXiv   pre-print
Different capacities are defined in different ways, and so relations between capacities often lead to surprising relations between different aspects of symplectic geometry and Hamiltonian dynamics.  ...  (ii) The function c(a)/a is nonincreasing. The first property follows directly from the (Monotonicity) axiom.  ...  One part of his pioneering work has grown into what is now called Gromov-Witten theory, see e.g. [73] for an introduction.  ...

Geometry of Schrödinger space-times II: particle and field probes of the causal structure

Matthias Blau, Jelle Hartong, Blaise Rollier
2010 Journal of High Energy Physics  
In particular, we provide a codimension 2 isometric embedding which naturally gives rise to the previously introduced global coordinates.  ...  under {H, C, D, N } thought of as elements of so(2, 2) via the above embedding of Lie algebras.  ...  Thus N can either arise from a null translation in the translational part of the isometry algebra of the embedding space or from a null rotation.  ...

Network Geometry [article]

2020 arXiv   pre-print
Yet the geometry induced by shortest path distances in a network is definitely not its only geometry.  ...  Other forms of network geometry are the geometry of latent spaces underlying many networks, and the effective geometry induced by dynamical processes in networks.  ...  II offers a possible explanation and a mechanism for the routing of information in the brain.  ...

Gravitational Lensing By a Massive Object in a Dark Matter Halo. II. Shear, Phase, and Image Geometry [article]

Michal Karamazov, David Heyrovsky
2021 arXiv   pre-print
Building on the analysis of critical curves and caustics presented in the first part of this work, we proceed to explore the geometry of images formed by the lens.  ...  In the case of our lens model, we describe the occurrence of zero-shear points and specify the conditions under which they become umbilic points.  ...  From this value the shear decreases outward monotonically.  ...
