Emergence of L 7-branes and fuzzy S 4 in compactification scenarios of M ( atrix ) theory

Abstract

The M(atrix) theory contains membranes and longitudinal 5-branes (L5-branes) as extended objects. The transverse components of these brane solutions can be described by fuzzy CP (k = 1, 2), where k = 1 corresponds to spherical membranes and k = 2 to L5-branes of CP×S1 world-volume geometry. In addition to these, we show the existence of L7-branes of CP×S1… (More)
