Optimal Inequalities Characterizing Totally Real Submanifolds in Quaternionic Space Form

Mathematics
In the present paper, we investigate some pinching inequalities on the scalar curvature of a totally real submanifold in quaternionic space form that leads to a topological conclusion of the submanifold. In addition, we construct another inequality which

Space and its form

Проект Байкал
Space as an object of architectural knowledge and thinking does not yet exist, since no one has done the work of introducing it into the historical and genetic analysis.

Totally real submanifolds of a complex space form

International Journal of Mathematics and Mathematical Sciences, 1996
Totally real submanifolds of a complex space form are studied. In particular, totally real submanifolds of a complex number space with parallel mean curvature vector are classified.

Types of light and colour impact on architectural form in space

Архитектон
The article presents a current view on the essential role of color and light in the formation of an architectural space, in particular the types of influence light and color exert on architectural form in space.

CR-submanifolds of a locally conformal Kaehler space form

International Journal of Mathematics and Mathematical Sciences, 1994
(Bejancu [1,2]) The purpose of this paper is to continue the study of CR-submanifolds, and in particular of those of a locally conformal Kaehler space form (Matsumoto [3]).

The mixed 0-form/1-form anomaly in Hilbert space: pouring the new wine into old bottles

Journal of High Energy Physics, 2021
We study four-dimensional gauge theories with arbitrary simple gauge group with 1-form global center symmetry and 0-form parity or discrete chiral symmetry. We canonically quantize on 𝕋3, in a fixed background field gauging the 1-form symmetry.

The city and emptiness

Проект Байкал, 2021
The article presents the author’s phenomenological study of emptiness with regard to the urban space. Studying the cases of three historical cities, the author analyses the meanings of emptiness coming out against the background of fatal external threats.

Killing forms on symmetric spaces

Differential Geometry and its Applications, 2006
Killing forms on Riemannian manifolds are differential forms whose covariant derivative is totally skew--symmetric. We show that a compact simply connected symmetric space carries a non--parallel Killing $p$--form ($p\ge2$) if and only if it isometric to a Riemannian product $S^k\times N$, where $S^k$ is a round sphere and $k>p$.

Making Space for Painting

Sillages Critiques, 2023
Like the frame, the spaces of painting are constructions that factor into the (re)production of the limits of the pictorial world. How these spaces are viewed – when they are acknowledged as there at all – is largely overlooked in favor of a focus on the
