Compactness of supermassive dark objects at galactic centers* [PDF]
Canadian journal of physics (Print), 2022 We define compactness of a gravitational lens as the scaled closest distance of approach (i.e., $r_0/M$) of the null geodesic giving rise to an image.

Compactness bounds in general relativity [PDF]
Physical Review D, 2022 A foundational theorem due to Buchdahl states that, within General Relativity (GR), the maximum compactness C ≡ GM/ ( Rc 2 ) of a static, spherically symmetric, perfect fluid object of mass M and radius R is C = 4 / 9.

Compactness of brane moduli and the String Lamppost Principle in d > 6 [PDF]
Journal of High Energy Physics, 2021 We demonstrate the validity of the String Lamppost Principle — that all consistent theories of quantum gravity are in the String Landscape — for supersymmetric theories in d > 6 using compactness and connectedness of the moduli space of small instantons,

A model test study of the instability of loess fill slope under different compactness
Shuiwen dizhi gongcheng dizhi, 2022 Loess fill slope is prone to landslide under the condition of rainfall infiltration. The influence of compaction degree under rainfall infiltration on the deformation and failure mechanism and the instability mode and sliding mechanism of loess fill ...

A class of operator related weighted composition operators between Zygmund space [PDF]
AUT Journal of Mathematics and Computing, 2021 Let $\mathbb {D}$ be the open unit disk in the complex plane $\mathbb{C}$ and $H(\mathbb{D})$ be the set of all analytic functions on $\mathbb{D}$. Let $u, v\in H(\mathbb{D})$ and $\varphi$ be an analytic self-map of $\mathbb{D}$.

Extrapolation of compactness on weighted spaces [PDF]
Revista matemática iberoamericana, 2020 Let $T$ be a linear operator that, for some $p_1\in(1,\infty)$, is bounded on $L^{p_1}(\tilde w)$ for all $\tilde w\in A_{p_1}(\mathbb R^d)$ and in addition compact on $L^{p_1}(w_1)$ for some $w_1\in A_{p_1}(\mathbb R^d)$. Then $T$ is bounded and compact

DO POST-SOCIALIST URBAN AREAS MAINTAIN THEIR SUSTAINABLE COMPACT FORM? ROMANIAN URBAN AREAS AS CASE STUDY [PDF]
Journal of Urban and Regional Analysis, 2022 The compact city is regarded as an important concept in promoting sustainable development, especially within the European Union. The socialist urban planning system maintained a high compactness of the urban areas through almost exclusive predominance of

Compactness on Soft Topological Ordered Spaces and Its Application on the Information System
Journal of mathematics, 2021 It is well known every soft topological space induced from soft information system is soft compact. In this study, we integrate between soft compactness and partially ordered set to introduce new types of soft compactness on the finite spaces and ...

Toeplitz operators between large Fock spaces in several complex variables
AIMS Mathematics, 2022 Let $ \omega $ belong to the weight class $ \mathcal{W} $, the large Fock space $ \mathcal{F}_{\omega}^{p} $ consists of all holomorphic functions $ f $ on $ \mathbb{C}^{n} $ such that the function $ f(\cdot)\omega(\cdot)^{1/2} $ is in $ L^p(\mathbb{C ...
