Torus actions, Morse homology, and the Hilbert scheme of points on affine space [PDF]
Épijournal de Géométrie Algébrique, 2021 We formulate a conjecture on actions of the multiplicative group in motivic homotopy theory. In short, if the multiplicative group G_m acts on a quasi-projective scheme U such that U is attracted as t approaches 0 in G_m to a closed subset Y in U, then ...

On spaces of maps between complex projective spaces [PDF]
Proceedings of the American Mathematical Society, 1984 When 1 ⩽ m ⩽ n 1 \leqslant m \leqslant n , the space M ( P m , P n ) M({P^m},{P^n}) of maps of complex projective m m -space

Junctions of mass-deformed nonlinear sigma models on SO(2N)/U(N) and Sp(N)/U(N). Part II
Journal of High Energy Physics, 2020 We construct three-pronged junctions of mass-deformed nonlinear sigma models on SO(2N)/U(N) and Sp(N )/U(N ) for generic N. We study the nonlinear sigma models on the Grassmann manifold or on the complex projective space.

Projection bodies in complex vector spaces
Advances in Mathematics, 2011 The space of Minkowski valuations on an m-dimensional complex vector space which are continuous, translation invariant and contravariant under the complex special linear group is explicitly described. Each valuation with these properties is shown to satisfy geometric inequalities of Brunn-Minkowski, Aleksandrov-Fenchel and Minkowski type.

An Information Quantity in Pure State Models
Entropy, 2022 When we consider an error model in a quantum computing system, we assume a parametric model where a prepared qubit belongs. Keeping this in mind, we focus on the evaluation of the amount of information we obtain when we know the system belongs to the ...

A Dual of the Chow Transformation
Complex Manifolds, 2018 We define a dual of the Chow transformation of currents on the complex projective space. This transformation factorizes a left inverse of the Chow transformation and its composition with the Chow transformation is a right inverse of a linear diferential ...

he deformation pseudotensor of connections in cocongruence K (n - m)m
Дифференциальная геометрия многообразий фигур, 2023 The Grassmann manifold is the set of all -dimensional planes of an -dimensional projective space, with dim. One of the submanifolds of the Grassmann manifold is a complex of -planes if the dimension of the complex exceeds the difference .

Almost complex structures on complex projective spaces [PDF]
Transactions of the American Mathematical Society, 1974 In this paper we classify the almost complex structures on a complex projective space as roots of a certain polynomial equation.

Riemann surfaces in complex projective spaces [PDF]
Proceedings of the American Mathematical Society, 1972 The complex projective line and the complex quadric are the only compact Riemann surfaces in the complex projective plane with constant scalar normal curvature.
