Applications of perturbations on accretive mappings to nonlinear elliptic systems involving (p,q)-Laplacian

Wei, Li; Agarwal, R.P.; Wong, P.J.Y. (Нелінійні коливання, 2009)

Using perturbation results on sums of ranges of nonlinear accretive mappings of Calvert and Gupta, we present some abstract results about the existence of solutions of nonlinear Neumann elliptic systems involving (p, ...
Asymptotic behavior of positive solutions of fourth-order nonlinear difference equations

Agarwal, R.P.; Manojlović, J.V. (Український математичний журнал, 2008)
Eigenvalue characterization of a system of difference equations

Agarwal, R.P.; O'Regan, D.; P. J. Y. Wong (Нелінійні коливання, 2004)

We consider the following system of difference equations: ui(k) = λ∑gi(k, l)Pi(l, u1(l), u2(l), . . . , un(l)), k ∈ {0, 1, . . . }, 1 ≤ i ≤ n, where λ > 0 and T ≥ N ≥ 0. Our aim is to determine those values of λ such ...
Existence of local and global solutions of fractional order differential equations

Muslim, M.; Conca, C.; Agarwal, R.P. (Нелінійні коливання, 2011)

In this paper we shall study the existence of local and global mild solutions of the fractional order differential equations in an arbitrary Banach space by using the semigroup theory and Schauder’s fixed point theorem. ...
Fixed point theory for weakly sequentially upper semicontinuous maps with applications to differential inclusions

Agarwal, R.P.; O'Regan, D. (Нелінійні коливання, 2002)

We present new fixed point theorems for weakly sequentially upper semicontinuous maps. These results are then used to establish existence principles for second order differential equations and inclusions.
Hybrid-type generalized multivalued vector complementarity problems

Agarwal, R.P.; Ahmad, M.K.; Salahuddin (Український математичний журнал, 2013)

We introduce a new type of generalized multivalued vector complementarity problems with moving pointed cone. We discuss the existence results for generalized multivalued vector complementarity problems under inclusive ...
Interval Oscillation Criteria for Second-Order Nonlinear Differential Equations

Wan-Tong Li; Agarwal, R.P. (Український математичний журнал, 2001)

We present new interval oscillation criteria for certain classes of second-order nonlinear differential equations, which are different from the most known ones in the sense that they are based only on information on a ...
Optimal existence theory for single and multiple positive periodic solutions to functional differential equations

Jiang, D.; O'Regan, D.; Agarwal, R.P. (Нелінійні коливання, 2003)

This paper deals with a new optimal existence theory for single and multiple positive periodic solutions to functional differential equations by employing a fixed point theorem in cones. We illustrate our theory by ...
Oscillation of certain fourth order functional differential equations

Agarwal, R.P.; Grace, S.R.; O’Regan, D. (Український математичний журнал, 2007)

Some new criteria for the oscillation of fourth-order nonlinear functional differential equations of the special form are established.
