60. A Weighted Sobolev-Poincare's Inequality on Infinite Networks

Author

Murakami, Atsushi and Yamasaki, Maretsugu

Subjects
Infinite Network, Sobolev-Poincare's Inequality, Mathematics::Spectral Theory, the Discrete Laplacian, the Smallest Eigen-value
Abstract

Inequalities on networks have played important roles in the theory of networks. We study the famous Sobolev-Poincare's inequality on infinite net-works in the weighted form. This inequality is closely related to the smallest eigenvalue of a weighted discrete Laplacian. We give a dual characterization for the smallest eigenvalue.

61. Inequalities on Infinite Networks

Author

Murakami, Atsushi and Yamasaki, Maretsugu

Subjects
Infinite Network, Discrete Inequalities, Eigenvalue of Discrete Laplacian
Abstract

Inequalities on networks have played important roles in the theory of netwoks. We study several famous inequalities on networks such as Wirtinger's inequality, Hardy's inequality, Poincare-Sobolev's inequality and the strong isoperimetric inequality, etc. These inequalities are closely related to the smallest eigenvalue of weighted discrete Laplacian. We discuss some relations between these inequalities and the potential-theorerteic magnitude of the ideal boundary of an infinite network.

64. An Introduction of Kuramochi Boundary of an Infinite Network

Author

Murakami, Atsushi and Yamasaki, Maretsugu

Subjects
discrete potential, Infinite network, Mathematics::Spectral Theory, Kuramochi boundary
Abstract

We develop a theory of Kuramochi boundary on an infinite network. The discrete Laplacian and the Dirichlet sum in the discrete potential theory on an infinite network play an important role in our study.

68. Some Properties of Reproducing Kernels on an Infinite Network

Author

Murakami, Atsushi, Yamasaki, Maretsugu, and Yone-e, Yoshinori

Abstract

It is shown that the extremal length of an infinite network satisfies a triangle inequality. A new formula for the extremal distance between two nodes will be given with the aid of a reproducing kernel. We shall discuss extremum problems related to Green functions.

72. Nonlinear Potentials on an Infinite Network

Author

Murakami, Atsushi and Yamasaki, Maretsugu

Abstract

The aim of this paper is to study some properties, of Dirichlet potentials and pure potentials of order p on an infinite network. It will be shown that several assumptions in the theory of general nonlinear potential theory are fulfilled in our case. The space of Dirichlet potentials of order p will play a crucial role in our study if the network is hyperbolic of order p. A nonlinear version of Cartan's domination principle will be shown with elementary properties of p-superharmonic functions.

73. Extremal Problems with respect to Ideal Boundary Components of an Infinite Network(II)

Author

Murakami, Atsushi and Yamasaki, Maretsugu

Abstract

Several extremum problems will be studied with the constraint qualification related to ideal boundary components of an infinite network. We shall give a generalized inverse relation between the extremal length and the extremal width of the network relative to ideal boundary components.
