Oscillation of second-order noncanonical neutral differential equations with distributed deviating arguments

In this thesis, we first focus on the definition, classification and examples of functional differential equations. Then, some classes of neutral differential equations with distributed deviating arguments discussed in the literature are included. Based on the studies in the literature, a class of neutral differential equations with distributed deviating arguments is considered and new sufficient conditions for the oscillation of solutions of the equation considered are given. Finally, examples explaining the results obtained are given and some suggestions are proposed to contribute to the literature.
