# SageMath code for working with p-adic field 5.1.5.6a1.1. # Define the p-adic field: Prec = 100 # Default precision of 100 Q5 = Qp(5, Prec); x = polygen(QQ) K. = Q5.extension(x^5 + 10*x^2 + 5) # Defining polynomial: K.defining_polynomial() # Base field Qp: K.base() # Degree over Qp: K.absolute_degree() # Ramification index: K.absolute_e() # Residue field degree (Inertia degree): K.absolute_f() # Maximal unramified subextension: K.maximal_unramified_subextension() # Roots of unity: len(K.roots_of_unity())
