The initial value problem for the nonlinear Klein-Gordon equation with various cubic nonlinearities depending on v, v t , v x , v xx , v tx and having a suitable nonresonance

The system evolves from its initial state without being further affected by diffusion until the next pulse appears; Δx i x i nτ − x i nτ, and x i nτ represents the density

Then by applying specialization maps of admissible fundamental groups and Nakajima’s result concerning ordinariness of cyclic ´ etale coverings of generic curves, we may prove that

Thus, Fujita’s result says that there are no global, nontrivial solutions of (1.3) whenever the blow up rate for y(t) is not smaller than the decay rate for w(x, t) while there are

The orthogonality test using S t−1 (Table 14), M ER t−2 (Table 15), P P I t−1 (Table 16), IP I t−2 (Table 17) and all the variables (Table 18) shows that we cannot reject the
