Tachyons in compact spaces [PDF]
Journal of High Energy Physics, 2005 We discuss condensations of closed string tachyons localized in compact spaces. Time evolution of an on-shell condensation is naturally related to the worldsheet RG flow. Some explicit tachyonic compactifications of Type II string theory is considered, and some of them are shown to decay into supersymmetric theories known as the little string theories.

Finite Unions of D-Spaces and Applications of Nearly Good Relation
Discrete Dynamics in Nature and Society, 2013 Some results are obtained on finite unions of D-spaces. It is proved that if a space is the union of finitely many locally compact D-subspaces, then it is a D-space. It follows that a space is a D-space if it is the union of finitely many locally compact

Approximation and Schur properties for Lipschitz free spaces over compact metric spaces
, 2015 We prove that for any separable Banach space $X$, there exists a compact metric space which is homeomorphic to the Cantor space and whose Lipschitz-free space contains a complemented subspace isomorphic to $X$.

Novel Classes of Bipolar Soft Generalized Topological Structures: Compactness and Homeomorphisms
Fuzzy Information and EngineeringThe purpose of this paper is to define bipolar soft generalized compact sets and bipolar soft generalized compact spaces. The structures of g~~-centralized bipolar soft generalized closed sets collection in a bipolar soft generalized compact space are ...

Quasi $M$-compact spaces [PDF]
Czechoslovak Mathematical Journal, 1996 All spaces are Tychonoff, and \(\alpha\) is an infinite cardinal number. Recall that a space \(X\) is said to be initially \(\alpha\)-compact if every open cover of \(X\) of cardinality \(\leq\alpha\) has a finite subcover, and given a subset \(\emptyset\neq M\subseteq\alpha^*= \beta(\alpha)\smallsetminus\alpha\), a space \(X\) is \(M\)-compact (quasi \

Performance Analysis of Large-Scale Digital Phased Array Mixed-ADC Receiver in Compact Space
天地一体化信息网络In order to evaluate the performance of large-scale digital phased array mixed-ADC receivers under the influence of mutual coupling effects in compact spaces, a performance analysis method was proposed.
