Extending Invariant Solutions

چکیده
In this paper we show that an invariant solution for normal form games can be extended uniquely to an invariant solution for strategic form games. This result has Ž . the following consequence for the reduction of a normal form game. Suppose that Ž the pure strategies are removed that are payoff equivalent with some possibly . mixed strategy. Then, if one is concerned with an invariant solution, a further reduction by identifying for each player arbitrary payoff-equivalent strategies is not necessary.

$PI$-extending modules via nontrivial complex bundles and Abelian endomorphism rings
A module is said to be $PI$-extending provided that every projection invariant submodule is essential in a direct summand of the module. In this paper, we focus on direct summands and indecomposable decompositions of $PI$-extending modules. To this end, we provide several counter examples including the tangent bundles of complex spheres of dimensions bigger than or equal to 5 and certain hyper ...
متن کاملModules whose direct summands are FI-extending
A module $M$ is called FI-extending if every fully invariant submodule of $M$ is essential in a direct summand of $M$. It is not known whether a direct summand of an FI-extending module is also FI-extending. In this study, it is given some answers to the question that under what conditions a direct summand of an FI-extending module is an FI-extending module?
متن کاملA nonlinear second order field equation – similarity solutions and relation to a Bellmann-type equation - Applications to Maxwellian Molecules
In this paper Lie’s formalism is applied to deduce classes of solutions of a nonlinear partial differential equation (nPDE) of second order with quadratic nonlinearity. The equation has the meaning of a field equation appearing in the formulation of kinetic models. Similarity solutions and transformations are given in a most general form derived to the first time in terms of reciprocal Jacobian...
متن کاملGeometric Stability Analysis for Periodic Solutions of the Swift-Hohenberg Equation
In this paper we describe invariant geometrical structures in the phase space of the Swift-Hohenberg equation in a neighborhood of its periodic stationary states. We show that in spite of the fact that these states are only marginally stable (i.e., the linearized problem about these states has continuous spectrum extending all the way up to zero), there exist finite dimensional invariant manifo...
متن کاملGeneralized Group Actions in a Global Setting
We study generalized group actions on differentiable manifolds in the Colombeau framework, extending previous work on flows of generalized vector fields and symmetry group analysis of generalized solutions. As an application, we analyze group invariant generalized functions in this setting. Mathematics Subject Classification (2000): Primary: 46F30; secondary: 46T30, 35A30, 58E40
