,-Conditional Symmetries of Reaction-Diffusion Systems,ns is presented. We generalize the standard definition of .-conditional symmetry by introducing the notion of .-conditional symmetry of the .-th type and show that different types of symmetry of a given system generate a hierarchy of conditional symmetry operators. It is shown that .-conditional sym

,Conditional Symmetries and Exact Solutions of Diffusive Lotka–Volterra Systems,provide their biological interpretation. An exhaustive description of .-conditional symmetries of the first type (a special subset of nonclassical symmetries) of these nonlinear systems is derived. An essential part of this chapter is devoted to the construction of exact solutions of the systems in
