Branes are Waves and Monopoles

Understand

In a recent paper it was shown that fundamental strings are null waves in Double Field Theory.

• Similarly, membranes are waves in exceptional extended geometry.
• Here the story is continued by showing how various branes are Kaluza-Klein monopoles of these higher dimensional theories.
• Examining the specific case of the E7 exceptional extended geometry, we see that all branes are both waves and monopoles.
