The Covering Numbers of Mycielski Ideals Are All Equal
The Mycielski ideal Mk is defined to consist of all sets A ⊆ k such that {f ↾ X : f ∈ A} 6= k for all X ∈ [ω]0 . It will be shown that the covering numbers for these ideals are all equal. However, the covering numbers of the closely associated Ros lanowski ideals will be shown to be consistently different.

متن کاملOn the total graph of Mycielski graphs, central graphs and their covering numbers
The technique of counting cliques in networks is a natural problem. In this paper, we develop certain results on counting of triangles for the total graph of the Mycielski graph or central graph of star as well as completegraph families. Moreover, we discuss the upper bounds for the number of triangles in the Mycielski and other well known transformations of graphs. Finally, it is shown that th...

BRONCHOCONSTRICTION IS A CARDINAL feature of asthma. It involves airway narrowing, increase in airway resistance, impairment of breathing, and can in very severe cases even lead to death. The severe narrowing of the airway lumen during bronchoconstriction is caused by a shortening of the airway smooth muscle in response to agonists or vagal stimulation. However, does a simple stimulus-response ...
