On the boundary of 2-dimensional ideal polyhedra

Similarity:
It is proved that for every two points in the visual boundary of the universal covering of a -dimensional ideal polyhedron, there is an infinity of paths joining them.
On some ideal related to the ideal (v 0 )
Piotr Kalemba (2015)
Open Mathematics
Similarity:
The ideal (v0) is known in the literature and is naturally linked to the structure [ω]ω. We consider some natural counterpart of the ideal (v0) related in an analogous way to the structure Dense(ℚ) and investigate its combinatorial properties. By the use of the notion of ideal type we prove that under CH this ideal is isomorphic to (v0).

On the ideal triangulation graph of a punctured surface
Mustafa Korkmaz, Athanase Papadopoulos (2012)
Annales de l’institut Fourier
Similarity:
We study the ideal triangulation graph of an oriented punctured surface of finite type. We show that if is not the sphere with at most three punctures or the torus with one puncture, then the natural map from the extended mapping class group of into the simplicial automorphism group of is an isomorphism. We also show that the graph of such a surface , equipped with its natural simplicial metric is not Gromov hyperbolic. We also show that if the triangulation graph of two...
Positive Implicative Soju Ideals in BCK-Algebras
Xiao Long Xin, Rajab Ali Borzooei, Young Bae Jun (2019)
Bulletin of the Section of Logic
Similarity:
The notion of positive implicative soju ideal in BCK-algebra is introduced, and several properties are investigated. Relations between soju ideal and positive implicative soju ideal are considered, and characterizations of positive implicative soju ideal are established. Finally, extension property for positive implicative soju ideal is constructed.
