Let F t denote all sets of size tthat contain a set of F. Then jF tj jFj. Proof Use Theorem 4 to nd a function that maps sets of size 1 into sets of size 2 injectively. WebIn this paper, we introduce the concept of a generalized Hopf–Ore extension of a Hopf group-coalgebra and give the necessary and sufficient conditions for the Ore extension of a Hopf group-coalgebra to be a Hopf group-coalgebra. Moreover, an isomorphism theorem on generalized Hopf group-coalgebra Ore extensions is given and specific cases in a simple …

WebMar 1, 1992 · Ore (Math. Ann. 99, 1928, 84-117) developed a method for obtaining the absolute discriminant and the prime-ideal decomposition of the rational primes in a number field K. The method, based on Newton's polygon techniques, worked only when certain polynomials fs ( Y), attached to any side S of the polygon, had no multiple factors. http://cgm.cs.mcgill.ca/~godfried/teaching/dm-reading-assignments/Ore-Theorem.pdf
