Results 21 to 30 of about 684 (97)
, 2016 We demonstrate that some recent results regarding the connection between the convexity of the map t → f (t) and the sign of Δa f (t) , with 2 < ν < 3 , can be improved.

Some discrete Poincaré‐type inequalities
International Journal of Mathematics and Mathematical Sciences, Volume 25, Issue 7, Page 479-488, 2001., 2001 Some discrete analogue of Poincaré‐type integral inequalities involving many functions of many independent variables are established. These in turn can serve as generators of further interesting discrete inequalities.

International Journal of Mathematics and Mathematical Sciences, Volume 23, Issue 4, Page 261-270, 2000., 2000 An open problem given by Kocic and Ladas in 1993 is generalized and considered. A sufficient condition is obtained for each solution to tend to the positive steady‐state solution of the systems of nonlinear Volterra difference equations of population models with diffusion and infinite delays by using the method of lower and upper solutions and monotone

Solvability of a nonlinear second order conjugate eigenvalue problem on a time scale
Abstract and Applied Analysis, Volume 5, Issue 2, Page 91-99, 2000., 2000 We consider the nonlinear second order conjugate eigenvalue problem on a time scale: y ΔΔ(t) + λa(t)f(y(σ(t))) = 0, t ∈ [0, 1], y(0) = 0 = y(σ(1)) . Values of the parameter λ (eigenvalues) are determined for which this problem has a positive solution. The methods used here extend recent results by allowing for a broader class of functions for a(t).

Discrete, Continuous, Delta, Nabla, and Diamond-Alpha Opial Inequalities
, 2015 In this paper, we prove some new diamond-alpha dynamic inequalities of Opial type with one and with two weight functions on time scales. These results contain as special cases improvements of results given in the literature, and these improvements are ...
