N = 4, d = 1 Supersymmetric Hyper-Kähler Sigma Models and Non-Abelian Monopole Background	2011	9	.pdf	application/pdf	5845	284	66	In what follows, to make some expressions more transparent, we will use, sometimes, the following stereographic coordi- nates for the bosonic components of hypermultiplet (2.21) and tensor supermultiplet (2.14): q11 = e 1 2 (u−iφ)√ 1 + ΛΛ Λ, q21 = − e 1 2 (u−iφ)√ 1 + ΛΛ , q22 = ( q11 ) Indeed, from (2.17) and (2.23) one may get the fol- lowing expression for A: A = 1 f [ φ̇+ ∂ ∂va f(λσaλ̄)−Bav̇a ] , (3.6) where f = 1 |v| , and , B1 = − v2(v3 + |v|) (v21 + v22)|v| , B2 = v1(v3 + |v|) (v21 + v22)|v| , B3 = 0.
