The lower algebraic K-theory of the finite subgroups of these groups up to eleven strings is computed using a wide variety of tools. Many of the techniques extend to the general case, and the results reveal new K-theoretical phenomena with respect to the previous study of other families of groups. The second part of the manuscript focusses on the case of the 4-string braid group of the 2-sphere, which is shown to be hyperbolic in the sense of Gromov. This permits the computation of the infinite maximal virtually cyclic subgroups of this group and their conjugacy classes, and applying the fact that this group satisfies the Fibred Isomorphism Conjecture of Farrell and Jones, leads to an explicit calculation of its lower K-theory. Researchers and graduate students working in K-theory and surface braid groups will constitute the primary audience of the manuscript, particularly those interested in the Fibred Isomorphism Conjecture, and the computation of Nil groups and the lower algebraic K-groups of group rings. The manuscript will also provide a useful resource to researchers who wish to learn the techniques needed to calculate lower algebraic K-groups, and the bibliography brings together a large number of references in this respect. 410 0$aSpringerBriefs in Mathematics,$x2191-8201 606 $aGroup theory 606 $aK-theory 606 $aCommutative algebra 606 $aCommutative rings 606 $aGroup Theory and Generalizations 606 $aK-Theory 606 $aCommutative Rings and Algebras 615 0$aGroup theory. 615 0$aK-theory. 615 0$aCommutative algebra. 615 0$aCommutative rings. 615 14$aGroup Theory and Generalizations. 615 24$aK-Theory. 615 24$aCommutative Rings and Algebras. 676 $a512.2 700 $aGuaschi$b John$4aut$4http://id.loc.gov/vocabulary/relators/aut$0767918 702 $aJuan-Pineda$b Daniel$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aMillán López$b Silvia$4aut$4http://id.loc.gov/vocabulary/relators/aut 906 $aBOOK 912 $a9910300105203321 996 $aThe Lower Algebraic K-Theory of Virtually Cyclic Subgroups of the Braid Groups of the Sphere and of ZB4(S2)$91910226 997 $aUNINA
