Projective bundles and blowing ups
Comptes Rendus. Mathématique, 2021 We study the blowing up $\widetilde{X}$ of a smooth projective variety $X$ along a smooth center $B$ that is equipped with a projective bundle structure over a variety $Z$. If $B$ is a point, then $X$ is a projective space. If the Picard number $\rho (X)$

DEGENERATION OF ENDOMORPHISMS OF THE COMPLEX PROJECTIVE SPACE IN THE HYBRID SPACE [PDF]
Journal of the Institute of Mathematics of Jussieu, 2016 We consider a meromorphic family of endomorphisms of degree at least 2 of a complex projective space that is parameterized by the unit disk. We prove that the measure of maximal entropy of these endomorphisms converges to the equilibrium measure of the ...

Engineering and Technology Journal, 2009 The purpose of this work is to give some definitions and prove some theorems onprojective 3-space S=PG(3,K) over a field K.Also, the principle of duality in S is given which state that any theorem true in theprojective 3-space concerned with the points ...

Characterization of generic projective space bundles and algebraicity of foliations [PDF]
Commentarii Mathematici Helvetici, 2017 In this paper we consider various notions of positivity for distributions on complex projective manifolds. We start by analyzing distributions having big slope with respect to curve classes, obtaining characterizations of generic projective space bundles

-expansion in critical ϕ3-theory on real projective space from conformal field theory [PDF]
, 2016 We use a compatibility between the conformal symmetry and the equations of motion to solve the one-point function in the critical ϕ3-theory (a.k.a. the critical Lee–Yang model) on the d = 6 − 𝜖 dimensional real projective space to the first nontrivial ...

On the quaternion projective space
Journal of Taibah University for Science, 2020 Apart from being a vital and exciting field in mathematics with interesting results, projective spaces have various applications in design theory, coding theory, physics, combinatorics, number theory and extremal combinatorial problems. In this paper, we

On the properties of the projective Lie algebras of rigid h-spaces H32 of the type {32}
Учёные записки Казанского университета: Серия Физико-математические науки, 2020 The five-dimensional pseudo-Riemannian spaces that admit infinitesimal projective transformations were studied. A general solution of the Eisenhart equation in the h-space H32 of non-constant curvature was found.

Effective cones of cycles on blow-ups of projective space [PDF]
, 2016 In this paper, we study the cones of higher codimension (pseudo)effective cycles on point blow-ups of projective space. We determine bounds on the number of points for which these cones are generated by the classes of linear cycles, and for which these ...

Gradient-like observer design on the Special Euclidean group SE(3) with system outputs on the real projective space [PDF]
IEEE Conference on Decision and Control, 2015 A nonlinear observer on the Special Euclidean group SE(3) for full pose estimation, that takes the system outputs on the real projective space directly as inputs, is proposed.

Frobenius-Seshadri constants and characterizations of projective space [PDF]
, 2017 We introduce higher-order variants of the Frobenius-Seshadri constant due to Mustaţă and Schwede, which are defined for ample line bundles in positive characteristic.
