Query: On a kind of Noether symmetries and conservation laws in k-cosymplectic
  field theory   This paper is devoted to studying symmetries of certain kinds of
k-cosymplectic Hamiltonian systems in first-order classical field theories.
Thus, we introduce a particular class of symmetries and study the problem of
associating conservation laws to them by means of a suitable generalization of
Noether's theorem.
