Principal Bundle Structure of Matrix Manifolds

open access: yesMathematics, 2021
In this paper, we introduce a new geometric description of the manifolds of matrices of fixed rank. The starting point is a geometric description of the Grassmann manifold Gr(Rk) of linear subspaces of dimension ...

Computably Based Locally Compact Spaces [PDF]

open access: yesLogical Methods in Computer Science, 2006
ASD (Abstract Stone Duality) is a re-axiomatisation of general topology in which the topology on a space is treated, not as an infinitary lattice, but as an exponential object of the same category as the original space, with an associated lambda-calculus.

Classification of All Non-Isomorphic Regular and Cuspidal Arm Anatomies in an Orthogonal Metamorphic Manipulator

open access: yesRobotics, 2020
This paper proposes a classification of all non-isomorphic anatomies of an orthogonal metamorphic manipulator according to the topology of workspace considering cusps and nodes.

On the Five-Dimensional Non-Extremal Reissner–Nordström Black Hole: Retractions and Scalar Quasibound States

open access: yesUniverse
In this paper, we examine the role played by topology, and some specific boundary conditions as well, on the physics of a higher-dimensional black hole.
