Transfer positive hemicontinuity and zeros, coincidences, and fixed points of maps in topological vector spaces

Fixed Point Theory and Applications, 2005
Let E be a real Hausdorff topological vector space. In the present paper, the concepts of the transfer positive hemicontinuity and strictly transfer positive hemicontinuity of set-valued maps in E are introduced (condition of strictly transfer positive ...

On some variational inequality-constrained control problems

Journal of Inequalities and Applications, 2022
In this paper, by considering some properties associated with scalar functionals of multiple-integral type, we study the well-posedness and generalized well-posedness for a new variational inequality-constrained optimization problems By using the set of ...

Nearly Contraction Mapping Principle for Fixed Points of Hemicontinuous Mappings [PDF]

ISRN Applied Mathematics, 2013
We extend the application of nearly contraction mapping principle introduced by Sahu (2005) for existence of fixed points of demicontinuous mappings to certain hemicontinuous nearly Lipschitzian nonlinear mappings in Banach spaces. We have applied certain results due to Sahu (2005) to obtain conditions for existence—and to introduce an asymptotic ...

Which misspecifications persist?

Theoretical Economics, Volume 18, Issue 3, Page 1271-1315, July 2023., 2023
We use an evolutionary model to determine which misperceptions can persist. Every period, a new generation of agents use their subjective models and the data generated by the previous generation to update their beliefs, and models that induce better actions become more prevalent.

A common‐value auction with state‐dependent participation

Theoretical Economics, Volume 17, Issue 2, Page 841-881, May 2022., 2022
This paper analyzes a common‐value, first‐price auction with state‐dependent participation. The number of bidders, which is unobservable to them, depends on the true value. For participation patterns with many bidders in each state, the bidding equilibrium may be of a “pooling” type—with high probability, the winning bid is the same across states and ...

The structure of equilibria in trading networks with frictions

Theoretical Economics, Volume 17, Issue 2, Page 801-839, May 2022., 2022
Several structural results for the set of competitive equilibria in trading networks with frictions are established: The lattice theorem, the rural hospitals theorem, the existence of side‐optimal equilibria, and a group‐incentive‐compatibility result hold with imperfectly transferable utility and in the presence of frictions.

On a Fixed Point Theorem for General Multivalued Mappings on Finite Sets with Applications in Game Theory

Journal of Mathematics, Volume 2022, Issue 1, 2022., 2022
We propose a new fixed point theorem that completely characterizes the existence of fixed points for multivalued maps on finite sets. Our result can be seen as a generalization of Abian’s fixed point theorem. In the context of finite games, our result can be used to characterize the existence of a Nash equilibrium in pure strategies and can therefore ...

Regularization method for Noor’s variational inequality problem induced by a hemicontinuous monotone operator [PDF]

Fixed Point Theory and Applications, 2012
في هذه الورقة، نقدم طريقة تنظيم لإيجاد حل لمشكلة عدم المساواة التباينية في نور التي يسببها مشغل رتيب نصف مستمر. علاوة على ذلك، يرتبط هذا الحل بمجموعة الصفر من التعيينات المعكوسة الرتيبة بقوة. وبالتالي، نظرًا لأننا لا نفترض الرتابة القوية للمشغل المدروس، فإن نتائجنا عامة وتوسع بعض النتائج المعروفة في الأدبيات.

Pairwise Stable Matching in Large Economies

Econometrica, Volume 89, Issue 6, Page 2929-2974, November 2021., 2021
We formulate a stability notion for two‐sided pairwise matching problems with individually insignificant agents in distributional form. Matchings are formulated as joint distributions over the characteristics of the populations to be matched. Spaces of characteristics can be high‐dimensional and need not be compact.
