CONTRACTING UNDER WEAK

2006
After many years of debate, in 2005 Brazilian environmentalists, religious groups, scientists, farmers and seed companies reached an agreement on the rules for biotechnology research in general and of genetic modified crops in particular. While the debate at the two houses of congress was carried, Brazilian soybean growers have already adopted genetic ...

Common Fixed Point Results of Set Valued Maps for Aφ-Contraction and Generalized ϕ-Type Weak Contraction [PDF]

Symmetry, 2019
The solutions for many real life problems may be obtained by interpreting the given problem mathematically in the form f(x)=x . One such example is that of the famous Borsuk–Ulam theorem in which, using some fixed point argument, it can be guaranteed ...

Coincidence and fixed point theorems for generalized (ψ,φ)-weak nonlinear contraction in ordered K-metric spaces

Computers and Mathematics With Applications, 2011
In this paper, we establish coincidence and fixed point theorems for a pair of mappings satisfying a new generalized (ψ,φ)-weak nonlinear contraction type condition in ordered K-metric spaces.

Some Applications of the Weak Contraction Principle

Letters in Nonlinear Analysis and its Applications
Recently we obtained several extensions of the Banach contraction principle. One of them is the weak contraction principle or the Rus-Hicks-Rhoades contraction principle or Theorem P.

Weak Contractions and Fixed Points

The College Mathematics Journal, 2015
SummaryThe notation of a contraction is an important concept in analysis. We explore here the weaker notion of a weak contraction in a variety of contexts, involving the reader throughout with questions to provide additional details or proofs, and suggest possible further areas of exploration.

A Note on Weak Stabilizability of Contraction Semigroups

SIAM Journal on Control and Optimization, 1978
A recent result on weak stabilizability is that the system $\dot x = Ax + Bu$, where A is the infinitesimal generator of a contraction semigroup over a Hilbert space H, and B is linear bounded, is ...

Collaborative innovation: weak commitments and unenforceable contracts

International Journal of Procurement Management, 2020
Innovation that crosses organisational boundaries, such as those between buyers and sellers, requires complementary investments of assets by participants. This creates a contracting problem with the possibility of opportunistic behaviour. We show that this problem can be overcome using the mechanism of weak commitments. In situations where both parties
