A short proof of a cross-intersection theorem of Hilton

Families A1, ...,Ak of sets are said to be cross-intersecting if Ai ∩ Aj 6= ∅ for any Ai ∈ Ai and Aj ∈ Aj , i 6= j. A nice result of Hilton that generalises the Erd®sKo-Rado (EKR) Theorem says that if r ≤ n/2 and A1, ..., Ak are cross-intersecting sub-families of ( [n] r ) , then

Extension of Krull's intersection theorem for fuzzy module

‎In this article we introduce $mu$-filtered fuzzy module with a family of fuzzy submodules.  It shows the relation between $mu$-filtered fuzzy modules and crisp filtered modules by level sets. We investigate fuzzy topology on the $mu$-filtered fuzzy module and apply that to introduce fuzzy completion. Finally we extend Krull's intersection theorem of fuzzy ideals by using concept $mu$-adic comp...

On the Security of O-PSI a Delegated Private Set Intersection on Outsourced Datasets (Extended Version)

In recent years, determining the common information privately and efficiently between two mutually mistrusting parties have become an important issue in social networks. Many Private set intersection (PSI) protocols have been introduced to address this issue. By applying these protocols, two parties can compute the intersection between their sets without disclosing any information about compone...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
