Abstract We study world-volume effective theories of five-branes in type II string theories.We determine PEA PROTEIN the bosonic zero-modes of the NS5-brane, the Kaluza-Klein monopole, the exotic Q5-, R5-branes and a space-filling brane, by direct calculations within the formalism of double field theory (DFT).We show that these zero-modes are Nambu-Goldstone modes associated with the spontaneously broken gauge symmetries in DFT.They are organized into the bosonic part of the six-dimensional N $$ mathcal{N} $$ = (1) vector and the N $$ mathcal{N} $$ = (2, 0) tensor multiplets.
Among other things, we examine the locally non-geometric R5-branes and Toddler space-filling branes that are characterized by the winding space.We also study effective theories of five-branes with string worldsheet instanton corrections.
