The torsion group
WebTorsion has risen from the ashes of The GB Group, which went under in 2015, leaving a £32m hotel unfinished in Leeds city centre. One of the fastest growing contractors and developers in the UK, Torsion was co-founded by chief executive Dan Spencer who had spent close to a decade with The GB Group and took its demise as an opportunity to … An element m of a module M over a ring R is called a torsion element of the module if there exists a regular element r of the ring (an element that is neither a left nor a right zero divisor) that annihilates m, i.e., r m = 0. In an integral domain (a commutative ring without zero divisors), every non-zero element is regular, so a torsion element of a module over an integral domain is one annihilated by a non-zero element of the integral domain. Some authors use this as the definitio…
