Query: Reduction and Hamiltonian aspects of a model for virus-tumour
  interaction in oncolytic virotherapy   We analyse the Hamiltonian structure of a system of first-order ordinary
differential equations used for modeling the interaction of an oncolytic virus
with a tumour cell population. The analysis is based on the existence of a
Jacobi Last Multiplier for the system and a time dependent first integral. For
suitable conditions on the model parameters this allows for the reduction of
the problem to a planar system of equations for which the time dependent
Hamiltonian flows are described. The geometry of the Hamiltonian flows are
finally investigated using the symplectic and cosymplectic methods.
