I will first give a brief introduction of the Grassmann algebra and a fermionic version of Ostrogradsky’s ghost, based on arXiv:1704.02717. Then I will introduce multiple scalar fields and Weyl fermion to construct a field theoretical extension of the previous work and derive sufficient (degeneracy) conditions to have an appropriate number of degrees of freedom for avoiding Ostrogradsky’s ghost. I will give a successful model, and the consistency between Hamiltonian and Lagrange formulation will be discussed as well. &br; |
