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

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.

Weak-Ensconcement for Shielded Base Contraction

Proceedings of the Twentieth International Conference on Principles of Knowledge Representation and Reasoning, 2023
In this article, we provide the weak version of ensconcement which characterizes an interesting family of Shielded base contractions. In turn, this characterization induces a class of AGM contractions satisfying certain postulates that we reveal here. Finally, we show a connection among the class of contractions given by our weak ensconcement and other

Weak contractor directions and weak directional contractions

Nonlinear Analysis: Theory, Methods & Applications, 1983
In this paper the author has proved some results in weak contractor directions and weak directional contractions in the narrow sense. He has given some results in fixed points.

Weak contractions and trace class perturbations

Operators and Matrices, 2007
An absolutely continuous contraction is said to be in the class A if it has isometric H∞ functional calculus. We present evidence in favor of the conjecture that the class A is invariant under trace-class perturbations. Mathematics subject classification (2000): 47L45, 47A45, 47A55, 47B10.

Best proximity of proximal \(\mathcal{F}^\ast\)-weak contraction

2022
Summary: Best proximity point theorems for self-mappings were investigated with different conditions on spaces for contraction mappings. In this paper, we prove best proximity point theorems for proximal \(\mathcal{F}^\ast\)-weak contraction mappings.

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 ...

Hyperinvariant Subspaces of Weak Contractions. II.

1988
This note is a continuation of [6]. We shall use the terminology and notation of [6]. Recall that an operator T on a (complex separable) Hilbert space H is said to have the property (L) if Hyplat(T) is the smallest complete lattice containing all subspaces of the forms Ker S and \(\overline {{\mathbf{Ran}}} {\text{ S}} = \overline {{\text{SH ...
