On Perfectly Meager Sets
We show that it is consistent that the product of perfectly meager sets is perfectly meager.
متن کامل1-perfectly Orientable Graphs and Graph Products
A graph G is said to be 1-perfectly orientable (1-p.o. for short) if it admits an orientation such that the out-neighborhood of every vertex is a clique in G. The class of 1-p.o. graphs forms a common generalization of the classes of chordal and circular arc graphs. Even though 1-p.o. graphs can be recognized in polynomial time, no structural characterization of 1-p.o. graphs is known. In this ...
متن کاملMeagre numbers raise genome questions
Journalists believe they do not work to agendas. They will report on therapeutic cloning one day and on its opponents the next, regardless of their own views. Nevertheless, strong agendas do on occasions dominate news coverage. February’s announcement of the human genome sequence is a case in point. On the Sunday before Celera Genomics published its version in Science, and the public consortium...
متن کاملExceptional Sets and Fiber Products
Exceptional sets where fibers have dimensions higher than the generic fiber dimension are of interest in mathematics and in application areas, such as the theory of overconstrained mechanisms. We show that fiber products promote such sets to become irreducible components, whereupon they can be found using techniques from numerical algebraic geometry for computing the irreducible decomposition. ...
