Let Φ be a 3-SAT formula. Let n be larger than both the number of variables and the number of clauses. We construct a bivariate constraint satisfaction problem from Φ as follows. Let (i, j) be an edge in E ⊆ [n]× [n] if and only if the i’th clause contains the j’th variable. Set k = 7. Think of every assignment ai ∈ [7] to a vertex on the left as representing one of the 7 satisfying assignments...
متن کاملNotes on Virtualization (10)

Formally, distributions are usually defined as continuous linear functions on a certain topological vector space of “test functions”. However, it is not surprising that useful mathematical objects such as distributions also have a natural, concrete description. We shall start from this viewpoint, and later explain the abstraction to topological vector spaces, and explain why the latter is impor...

investigate its toxicity to the rat. They noted that animals dying after sulphaguanidine showed goitres which on microscopical section were found to be due to hyperplasia and were practically free from colloid. The same effect was produced more or less by other sulpha drugs such as sulphadiazine and sulphapyridine, and Richter and Clisby (1942) showed that other sulphur compounds, notably thiou...
