In 1999 Kannan, Tetali and Vempala proposed a MCMC method to uniformly sample all possible realizations of a given graphical degree sequence and conjectured its rapidly mixing nature. Recently their conjecture was proved affirmative for regular graph

A permutation group $G$ on a set $A$ is $��$-homogeneous iff for all $X,Y\in [A]^��$ with $|A\setminus X|=|A\setminus Y|=|A|$ there is a $g\in G$ with $g[X]=Y$. $G$ is $��$-transitive iff for any injective function $f$ with $dom(f)\cup ra

We construct locally Lindelöf scattered P-spaces (LLSP spaces, for short) with prescribed widths and heights under different set-theoretic assumptions. We prove that there is an LLSP space of width $\omega_1$ and height $\omega_2$ and that it is rel

In this paper a hypergraph will be identified with the family of its edges. A hypergraph $\mathcal E$ possesses property $C(k,{\rho})$ iff $|\bigcap \mathcal E'|{\omega}$. Countable sets of cardinals, and sets of successor cardinals are nowhere stati

As it was introduced by Tkachuk and Wilson in [7], a topological space X is cellular-compact if for any cellular, i.e. disjoint, family $$\mathcal{U}$$ of non-empty open subsets of X there is a compact subspace $$K \subset X$$ such that $$K \cap U \n
It is an interesting, maybe surprising, fact that different dense subspaces of even "nice" topological spaces can have different densities. So, our aim here is to investigate the set of densities of all dense subspaces of a topological space $X$ that

We prove the following consistency result for cardinal sequences of length ω 3 : if GCH holds and λ ≥ ω 2 is a regular cardinal, then in some cardinal-preserving generic extension 2 ω = λ and for every ordinal η ω 3 and every sequence f =

Given a topological property P, we say that the space X is P-generated if for any subset A ⊂ X that is not open in X there is a subspace Y ⊂ X with property P such that A ∩ Y is not open in Y. (Of course, in this definition we could replace “

We explore a general method based on trees of elementary submodels in order to present highly simplified proofs to numerous results in infinite combinatorics. While countable elementary submodels have been employed in such settings already, we signif

The $${G_\delta}$$ -modification $${X_\delta}$$ of a topological space X is the space on the same underlying set generated by, i.e. having as a basis, the collection of all $${G_\delta}$$ subsets of X. Bella and Spadaro recently asked the following q
