This paper studies the properties of Nambu-Poisson geometry from the(n-l,k)-Dirac structure on a smooth manifold M.Firstly,we examine the automorphism group and infinitesimal on higher order Courant algebroid,to prove the integrability of infinitesimal Courant automorphism.Under the transversal smooth morphismΦ:N-→M and anchor mapping of M on(n-1,k)-Dirac structure,it's holds that the pullback(n-1,k)-Dirac structure on M turns out an(n-1,k)-Dirac structure on N.Then,given that the graph of Nambu-Poisson structure takes the form of(n-1,n-2)-Dirac structure,it follows that the single parameter variety of Nambu-Poisson structure is related to one variety closed n-symplectic form under gauge transformation.WhenΦ:N-→M is taken as the immersion mapping of(n-1)-cosymplectic submanifold,the pullback Nambu-Poisson structure on M turns out the Nambu-Poisson structure on N.Finally,we discuss the(n-1,O)-Dirac structure on M can be integrated into a problem of(n-1)-presymplectic groupoid.Under the mapping II:M-→M/H,the corresponding(n-1,O)-Dirac structure is F and E respectively.If E can be integrated into(n-1)-presymplectic groupoid(g,2),then there exists the only,such that the corresponding integral of F is(n-1)-presymplectic groupoid(g,). 展开更多

In this paper,we study the algebraic properties of the higher analogues of Courant algebroid structures on the direct sum bundle TM⊕∧nT*M for an m-dimensional manifold.As an application,we revisit Nambu-Poisson structures and multisymplectic structures.We prove that the graph of an(n+1)-vector fieldπis closed under the higher-order Dorfman bracket iffπis a Nambu-Poisson structure.Consequently,there is an induced Leibniz algebroid structure on∧nT*M.The graph of an(n+1)-formωis closed under the higher-order Dorfman bracket iffωis a premultisymplectic structure of order n,i.e.,dω=0.Furthermore,there is a Lie algebroid structure on the admissible bundle A∧nT*M.In particular,for a 2-plectic structure,it induces the Lie 2-algebra structure given in(Baez,Hoffnung and Rogers,2010). 展开更多
