Interplay Between Game Theory and Control Theory
An interrelationship between Game Theory and Control Theory is seeked. In
this respect two aspects of this relationship are brought up. To establish the
direct relationship Control Based Games and to establish the inverse
relationship Game Based Control are discussed. In the attempt to establish the
direct relationship Control Based Boolean Networks are discussed with the novel
technique of application of Semi Tensor Product of matrices in Differential
Calculus. For the inverse relationship H Infinity robust optimal control has
been discussed with the help of Dynamic Programming and Pontryagin Minimization
Principle.Comment: 29 pages no figure
Observability of Boolean Networks via Set Controllability Approach
The controllability and observability of Boolean control network(BCN) are two
fundamental properties. But the verification of latter is much harder than the
former. This paper considers the observability of BCN via controllability.
First, the set controllability is proposed, and the necessary and sufficient
condition is obtained. Then a technique is developed to convert the
observability into an equivalent set controllability problem. Using the result
for set controllability, the necessary and sufficient condition is also
obtained for the observability of BCN.Comment: 6 page
On Skew-Symmetric Games
By resorting to the vector space structure of finite games, skew-symmetric
games (SSGs) are proposed and investigated as a natural subspace of finite
games. First of all, for two player games, it is shown that the skew-symmetric
games form an orthogonal complement of the symmetric games. Then for a general
SSG its linear representation is given, which can be used to verify whether a
finite game is skew-symmetric. Furthermore, some properties of SSGs are also
obtained in the light of its vector subspace structure. Finally, a
symmetry-based decomposition of finite games is proposed, which consists of
three mutually orthogonal subspaces: symmetric subspace, skew-symmetric
subspace and asymmetric subspace. An illustrative example is presented to
demonstrate this decomposition.Comment: 31 pages,9 table
On Coset Weighted Potential Game
In this paper we first define a new kind of potential games, called coset
weighted potential game, which is a generalized form of weighted potential
game. Using semi-tensor product of matrices, an algebraic method is provided to
verify whether a finite game is a coset weighted potential game, and a simple
formula is obtained to calculate the corresponding potential function. Then
some properties of coset weighted potential games are revealed. Finally, by
resorting to the vector space structure of finite games, a new orthogonal
decomposition based on coset weights is proposed, the corresponding geometric
and algebraic expressions of all the subspaces are given by providing their
bases.Comment: 10 pages,1 figur
Expressing a Tensor Permutation Matrix in Terms of the Generalized Gell-Mann Matrices
We have shown how to express a tensor permutation matrix as a
linear combination of the tensor products of the -Gell-Mann
matrices. We have given the expression of a tensor permutation matrix as a linear combination of the tensor products of the Pauli
matrices.Comment: 15 pages, v2 minor grammatical changes and acknoledgemen
Approximation of The Constrained Joint Spectral Radius via Algebraic Lifting
This paper studies the constrained switching (linear) system which is a
discrete-time switched linear system whose switching sequences are constrained
by a deterministic finite automaton. The stability of a constrained switching
system is characterized by its constrained joint spectral radius that is known
to be difficult to compute or approximate. Using the semi-tensor product of
matrices, the matrix-form expression of a constrained switching system is shown
to be equivalent to that of a lifted arbitrary switching system. Then the
constrained joint/generalized spectral radius of a constrained switching system
is proved to be equal to the joint/generalized spectral radius of its lifted
arbitrary switching system which can be approximated by off-the-shelf
algorithms
A Note On Orthogonal Decomposition of Finite Games
Various decomposition of finite games have been proposed. The inner product
of vectors plays a key role in the decomposition of finite games. This paper
considers the effect of different inner products on the orthogonal
decomposition of finite games. We find that only when the compatible condition
is satisfied, a common decomposition can be induced by the standard inner
product and the weighted inner product. To explain the result, we studied the
existing decompositions, including potential based decomposition, zero-sum
based decomposition, and symmetry based decomposition.Comment: 4 pages, 2019 IEEE CDC conference paper (submitted
Expression of a Tensor Commutation Matrix in Terms of the Generalized Gell-Mann Matrices
We have expressed the tensor commutation matrix n\otimes n as linear
combination of the tensor products of the generalized Gell-Mann matrices. The
tensor commutation matrices 3\otimes 2 and 2\otimes 3 have been expressed in
terms of the classical Gell-Mann matrices and the Pauli matrices.Comment: 14 pages, Submitted v2:no changes in the body of the paper, just
