In this Letter we show numerical existence of O (4) Dirac-Born-Infeld (DBI) Textures living in (N + 1) dimensional spacetime. These defects are characterized by S-N -> S-3 mapping, generalizing the well-known Hopf fibration into pi(N)(S-3), for all N > 3. The nonlinear nature of DBI kinetic term provides stability against size perturbation and thus renders the defects having natural scale. (c) 2012 Elsevier B.V. All rights reserved.
