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.

A Remark on Structure of Projective Klingenberg Spaces over a Certain Local Algebra
Mathematics, 2019 This article is devoted to the projective Klingenberg spaces over a local ring, which is a linear algebra generated by one nilpotent element. In this case, subspaces of such Klingenberg spaces are described.

ON PROJECTIONS IN PROJECTIVE SPACES
Demonstratio Mathematica, 1998 Die Verff. betonen, daß eine projektive Kollineation \(\varphi\) eines projektiven Raumes \(PG(V)\), \(V\) ein Vektorraum der Dimension \(\geq 2\), auch dadurch definiert werden kann, daß \(\varphi|_U\) für einen wenigstens 2-dimensionalen linearen Unterraum \(U\) eine solche ist.

The $K$-theory of twisted multipullback quantum odd spheres and complex projective spaces [PDF]
Journal of Noncommutative Geometry, 2015 We find multipullback quantum odd-dimensional spheres equipped with natural $U(1)$-actions that yield the multipullback quantum complex projective spaces constructed from Toeplitz cubes as noncommutative quotients.

Trace-Class and Nuclear Operators
Concrete Operators, 2022 This paper explores the long journey from projective tensor products of a pair of Banach spaces, passing through the definition of nuclear operators still on the realm of projective tensor products, to the of notion of trace-class operators on a Hilbert ...

Isospin particle systems on quaternionic projective spaces [PDF]
, 2013 We construct the isospin particle system on $n$-dimensional quaternionic projective spaces in the presence of BPST-instanton by the reduction from the free particle on $(2n+1)$-dimensional complex projective space.

On the hypersurfaces contained in their Hessian
Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2019 This article presents the theory of focal locus applied to the hypersurfaces in the projective space which are (finitely) covered by linear spaces and such that the tangent space is constant along these spaces.

Determination of the characteristic parameters in the special collinear space in the general case [PDF]
Facta Universitatis. Series: Architecture and Civil Engineering, 2007 The projective space consists of the finitely and infinitely distant elements. The special collinear spaces in the general case, are set with five pairs of biunivocally associated points, so the quadrangle in the first space obtained by the three ...

Polar foliations on quaternionic projective spaces [PDF]
Tohoku mathematical journal, 2015 We classify irreducible polar foliations of codimension $q$ on quaternionic projective spaces $\mathbb H P^n$, for all $(n,q)\neq(7,1)$. We prove that all irreducible polar foliations of any codimension (resp.
