The Thomas gyration, in turn, allows the introduction of vectors into hyperbolic geometry, where they are called gyrovectors, in such a way that Einstein's velocity additions turns out to be a gyrovector addition. Einstein's addition thus becomes a gyrocommutative, gyroassociative gyrogroup operation in the same way that ordinary vector addition is a commutative, associative group operation. Some gyrogroups of gyrovectors admit scalar multiplication, giving rise to gyrovector spaces in the same way that some groups of vectors that admit scalar multiplication give rise to vector spaces. Furthermore, gyrovector spaces form the setting for hyperbolic geometry in the same way that vector spaces form the setting for Euclidean geometry. In particular, the gyrovector space with gyrovector addition given by Einstein's (Möbius') addition forms the setting for the Beltrami (Poincaré) ball model of hyperbolic geometry. The gyrogroup-theoretic techniques developed in this book for use in relativity physics and in hyperbolic geometry allow one to solve old and new important problems in relativity physics. A case in point is Einstein's 1905 view of the Lorentz length contraction, which was contradicted in 1959 by Penrose, Terrell and others. The application of gyrogroup-theoretic techniques clearly tilt the balance in favor of Einstein. 410 0$aFundamental theories of physics ;$vv. 117. 606 $aSpecial relativity (Physics) 606 $aGeometry, Hyperbolic 615 0$aSpecial relativity (Physics) 615 0$aGeometry, Hyperbolic. 676 $a530.11 700 $aUngar$b Abraham A$0850286 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910966444503321 996 $aBeyond the Einstein addition law and its gyroscopic Thomas precession$94389589 997 $aUNINA LEADER 00729nam0-2200253 --450 001 9911032676503321 005 20251013120633.0 100 $a20251013d1992----kmuy0itay5050 ba 101 0 $aita 102 $aIT 105 $aa 001yy 200 1 $aBarisani$ei collages$fEnrico Crispolti 210 $aPortici$cFrancesco Cusati arte contemporanea$dstampa 1992 215 $a79 p.$cill.$d31 cm 327 $acatalogo descrittivo delle opere 700 1$aBarisani,$bRenato$0154306 702 1$aCrispolti,$bEnrico$f<1933-2018> 801 0$aIT$bUNINA$gREICAT$2UNIMARC 901 $aBK 912 $a9911032676503321 952 $aDE FUSCO 1399$bRDF 1454$fDARST 959 $aDARST 996 $aBarisani$94444879 997 $aUNINA
