In mathematics, the Séminaire de Géométrie Algébrique du Bois Marie was an influential seminar run by Alexander Grothendieck. It was a unique phenomenon of research and publication outside of the main mathematical journals that ran from 1960 to 1969 at the IHÉS near Paris. (The name came from the small wood on the estate in Bures-sur-Yvette where the IHÉS was located from 1962.) The seminar notes were eventually published in twelve volumes, all except one in the Springer Lecture Notes in Mathematics series.
The material has a reputation of being hard to read for a number of reasons. More elementary or foundational parts were relegated to the EGA series of Grothendieck and Jean Dieudonné, causing long strings of logical dependencies in the statements. The style is very abstract and makes heavy use of category theory. Moreover, an attempt was made to achieve maximally general statements, while assuming that the reader is aware of the motivations and concrete examples.
The Sale of Goods Act 1979 (c 54) is an Act of the Parliament of the United Kingdom which regulated English contract law and UK commercial law in respect of goods that are sold and bought. The Act consolidated the original Sale of Goods Act 1893 and subsequent legislation, which in turn had codified and consolidated the law. Since 1979, there have been numerous minor statutory amendments and additions to the 1979 Act. It was replaced for consumer contracts from 1 October 2015 by the Consumer Rights Act 2015(c 15) but remains the primary legislation underpinning B2B transactions for selling / buying goods.
The Act applied to contracts where property in 'goods' were transferred or agreed to be transferred for a monetary consideration, in other words: where property (ownership) in personal chattels was sold.
Sections 2 to 15B concern how a contract is formed and, in particular, contains standardised implied terms in all contracts for sale.
