Nonexistence of global (positive) solutions of semilinear higher-order evolution inequalities [GRAPHICS] with k = 1, 2, . . . ., in cone-like domains is studied. The critical exponents q* are found and the nonexistence results are proved for 1 < q <less than or equal to> q*. Remark that the corresponding result for k = 1 (parabolic problem) is sharp.
