DESCRIPTION: In this on-going work\, we study p-brane dynamics from the vi
 ewpoint of multisymplectic geometry\, in which the standard symplectic 2-f
 orm is replaced by a closed non-degenerate (p+2)-form on a finite-dimensio
 nal extended phase space. In this setting\, graded Poisson brackets organi
 ze into an L∞-algebra\, providing a higher algebraic framework for brane
  observables that goes beyond the standard Lie algebraic description. I wi
 ll show that Poincaré invariance together with the existence of Hamiltoni
 an flows strongly constrains the admissible mass-shell conditions within t
 his framework\, recovering the Nambu–Goto constraint as a particular cas
 e. I will also discuss multi-coadjoint orbit constructions that parallel t
 he classical orbit method for particles.
