Approximate Efficient Solutions of the Vector Optimization Problem on Hadamard Manifolds via Vector Variational Inequalities
This article has two objectives. Firstly, we use the vector variational-like inequalities
problems to achieve local approximate (weakly) efficient solutions of the vector optimization problem
within the novel field of the Hadamard manifolds. Previously, we introduced the concepts of
generalized approximate geodesic convex functions and illustrated them with examples. We see the
minimum requirements under which critical points, solutions of Stampacchia, and Minty weak
variational-like inequalities and local approximate weakly efficient solutions can be identified,
extending previous results from the literature for linear Euclidean spaces. Secondly, we show
an economical application, again using solutions of the variational problems to identify Stackelberg
equilibrium points on Hadamard manifolds and under geodesic convexity assumptions
Convex Analysis and Chaos : The Third Symposium on Nonlinear Analysis, July 23-25, 1998 Josai University
We obtain minimax theorerns and the Nash equilibrium theorem forG-convex spaces. Our new results extend and unify a number of known results forparticular types of G-convex spaces. Finally, we compare our new results with thecelebrated minimax theorem of H.

Complex Variables, Complex Geometry and Complex Dynamical Systems
with a special focus on the exchange of ideas and methods among these areas. The
main topics of the workshop included Holomorphic Dynamics and Nevanlinna's Theory; -methods and Cohomologies; Plurisubharmonic Functions and Pluripotential Theory; Geometric Questions of Complex Analysis
A study of spirallike domains: polynomial convexity, Loewner chains and dense holomorphic curves
In this paper, we prove that the closure of a bounded pseudoconvex domain,
which is spirallike with respect to a globally asymptotic stable holomorphic
vector field, is polynomially convex. We also provide a necessary and
sufficient condition, in terms of polynomial convexity, on a univalent function
defined on a strongly convex domain for embedding it into a filtering Loewner
chain. Next, we provide an application of our first result. We show that for
any bounded pseudoconvex strictly spirallike domain in
and given any connected complex manifold , there exists a holomorphic map
from the unit disc to the space of all holomorphic maps from to .
This also yields us the existence of -universal map for
any generalized translation on , which, in turn, is connected to the
hypercyclicity of certain composition operators on the space of manifold valued
holomorphic maps.Comment: 25 pages, comments are welcom
A Discrete Characterization of the Solvability of Equilibrium Problems and Its Application to Game Theory
We state a characterization of the existence of equilibrium in terms of certain finite
subsets under compactness and transfer upper semicontinuity conditions. In order to derive some
consequences on game theory—Nash equilibrium and minimax inequalities—we introduce a weak
