We give su ffi cient conditions so that all solutions of di ff erential equations r t y t q t k y t p t y α g t f t , t ≥ t 0 , and r t y t q t k y t p t h y g t f t , t ≥ t 0 , are nonoscillatory. Depending on these criteria, some results which exist in[r]
Then ( 1.14 ) is oscillatory if p∗ > 1 / 4, and nonoscillatory if p ∗ < 1 / 4. The equation can be either oscillatory or nonoscillatory if either p∗ or p ∗ = 1 / 4. So the following question arises: can one extend the Hille-Kneser theorem to the half- linear dynamic equations L[r]
As a cone in R k+1 , each C µ induces a partial order ≤ µ on R k+1 by x ≤ µ y if and only if y − x ∈ C µ . We write x < µ y if x ≤ µ y and x = y . The strong ordering µ is defined by x µ y if and only if y − x ∈ int C µ . The ordering ≤ µ is called the discrete exponential ordering[r]

The aim of this work is to present numerical treatments to a complex order fractional nonlinear onedimensional problem of Burgers’ equations. A new parameter rt is presented in order to be consistent with the physical model problem. This parameter characterizes the existence of fractional structures[r]
