This can be made precise for the ring of continuous real-valued functions on a compact Hausdorff space, as well as for the ring of smooth functions on a smooth manifold ( see Serre – Swan theorem that says a finitely generated projective module over the space of smooth functions on a compact manifold is the space of smooth sections of a smooth vector bundle ).

Serre and conjecture

Bass ); the Borel-Serre compactification ; results on the number of points of curves over finite fields ; Galois representations in ℓ-adic cohomology and the proof that these representations have often a " large " image ; the concept of p-adic modular form ; and the Serre conjecture ( now a theorem ) on mod-p representations that made Fermat's last theorem a connected part of mainstream arithmetic geometry.

) In 1959, Serre formed the Grothendieck group construction for rings, and used it to prove a weak form of the conjecture.

Some mathematicians, therefore, do not recognize blackboard bold as a separate style from bold: Jean-Pierre Serre, for example, has publicly inveighed against the use of " blackboard bold " anywhere other than on a blackboard, and uses double-struck letters when writing bold on the blackboard, whereas his published works consistently use ordinary bold for the same symbols.
The climate is influenced by the mountainous and hilly relief of the region: cold in the area of Monte Pollino, temperate with a very limited temperature range in the area of Aspromonte, while the Sila and Serre massifs ensure greater humidity on the Tyrrhenian coast and a drier climate on the Ionian coast.
