Bundles over Quantum RealWeighted Projective Spaces
Axioms, 2012 The algebraic approach to bundles in non-commutative geometry and the definition of quantum real weighted projective spaces are reviewed. Principal U(1)-bundles over quantum real weighted projective spaces are constructed.

The concordance diffeomorphism group of real projective space
, 1974 Let Pe be r-dimensional real projective space with r odd, and let ro0 Diffl: Pe be the group of orientation preserving diffeomorphisms Pe -* Pe factored by the normal subgroup of those concordant (= pseudoisotopic) to the identity.

Data‐driven performance metrics for neural network learning
International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary Effectiveness of data‐driven neural learning in terms of both local mimima trapping and convergence rate is addressed. Such issues are investigated in a case study involving the training of one‐hidden‐layer feedforward neural networks with the extended Kalman filter, which reduces the search for the optimal network parameters to a state ...

A real-time photogrammetric algorithm for sensor and synthetic image fusion with application to aviation combined vision [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014 The paper addresses a promising visualization concept related to combination of sensor and synthetic images in order to enhance situation awareness of a pilot during an aircraft landing.

, 2006 We study the Euler characteristic modulo 2 of the manifold immersed in the multiple point set of the self-transverse immersions of the real projective space RPn and the Milnor manifold Hm,n in the sphere.

Characterization of affine links in the projective space [PDF]
arXiv, 2019 A projective link is a smooth closed 1-submanifold of the real projective space of dimension three. A projective link is said to be affine if it is isotopic to a link, which does not intersect some projective plane. The main result: a projective link is affine if and only if the fundamental group of its complement contains a non-trivial element of ...

A note on irreducible Heegaard diagrams
International Journal of Mathematics and Mathematical Sciences, 2006 We construct a Heegaard diagram of genus three for the real projective 3-space, which has no waves and pairs of complementary handles. The first example was given by Im and Kim but our diagram has smaller complexity.

Natural Perspective: Mapping Visual Space with Art and Science
Vision, 2018 Following its discovery in fifteenth-century Italy, linear perspective has often been hailed as the most accurate method of projecting three-dimensional visual space onto a two-dimensional picture plane.

Configuration spaces of complex and real spheres [PDF]
arXiv, 2014 We study the GIT-quotient of the Cartesian power of projective space modulo the projective orthogonal group. A classical isomorphism of this group with the Inversive group of birational transformations of the projective space of one dimension less allows one to interpret these spaces as configuration spaces of complex or real spheres.
