Title : Field theoretical extension of higher derivative fermionic theory
Abstract:
Next Monday, I will talk about our ongoing work : higher derivative fermionic field theory. 
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.
