Neste trabalho mostramos o importante teorema de Merkurjev- Suslin para o caso de 2-torção, seguindo o artigo [Mer06], que afirma que, para qualquer corpo F de característica diferente de 2, a 2-torção \'IND.2 Br\'(F) do grupo de Brauer de F é gerada pelas classes de álgebras de quatérnionsIn this work we show the important theorem of Merkurjev- Suslin for 2-torsion, following the paper [Mer06], which states that for any field F of characteristic not 2 the 2-torsion \'IND. 2 Br\'(F) of the Brauer Group of F is generated by the quaternion algebra classe
