On some non-linear elliptic differential-functional equations

Variable Dimension Complexes Part II: A Unified Approach to Some Combinatorial Lemmas in Topology

“…Our next lemma demonstrates the existence of stationary points (see Eaves [2], and Liithi Lemma (Hartman and Stampacchia [7], and Karamardian [8a], [8b], [9]). …”

On the Maximality of Sums of Nonlinear Monotone Operators

“…Some applications of this sort will be considered in §4. For the sake of applications to a class of variational inequalities studied in terms of hemicontinuity by Hartman-Stampacchia [8] and Browder [4], it will be useful to have, along with Theorems 1 and 2, the following special maximality theorem.…”

Iterative algorithm for strongly continuous semigroup of Lipschitz pseudocontraction mappings

“…The variational inequality problem was first introduced by Hartman and Stampacchia [9]. Then, the variational inequality has achieved an increasing attention in many research fields, such as mathematical programming, constrained linear and nonlinear optimization, automatic control, manufacturing system design, signal and image processing and the complementarity problem in economics and pattern recognition (see [4,7,8] and the references therein).…”
