On the Behavior of F-Rational Rings under Flat Base Change

✍ Florian Enescu 📂 Article 📅 2000 🏛 Elsevier Science 🌐 English ⚖ 159 KB

We examine the behavior of F-rationality under flat homomorphisms with geometrically F-rational fibres. The goal is to prove that if R ª S is a homomorphism with geometrically F-rational fibres and R is an F-rational ring, then S is an F-rational ring. We prove a stronger version of this under a mil

✍ Srikanth Iyengar 📂 Article 📅 1997 🏛 Elsevier Science 🌐 English ⚖ 270 KB

Projective resolutions of modules over a ring R are constructed starting from appropriate projective resolutions over a ring Q mapping to R. It is shown that such resolutions may be chosen to be minimal in codimension F 2, but not in codimension 3. This is used to obtain minimal resolutions for esse

We fix a prime p. It is a conjecture of Serre, cf. [S], that every odd, continuous, irreducible representation As notation, for a number field F, we denote by G F its absolute Galois group. We fix embeddings @: Q / Ä C and @ p : Q / Ä Q p , and denote by p the place above p fixed by @ p . If S is a

Poly-Schiff base containing bisthiazole rings (TAPDA) has been prepared from terephthalaldehyde and 2,2 -diamino-4,4-bisthiazole. It was found that the TAPDA polymer film is permeable to H 2 , O 2 , and N 2 and can be converted into an electrical conductor by pyrolysis at high temperature in nitroge
