-sectorial discrete Laplacians and recurrence of complex-weighted graphs

Anna Muranova

We consider complex-weighted graphs, whose edge weights belong to a sector in the complex plane. We show that the corresponding Dirichlet Laplacian is -sectorial, and, hence, ge…

Periodic discrete graphs with prescribed spectrum

Andrii Khrabustovskyi, Anna Muranova

We construct a periodic weighted graph whose discrete Laplacian has a spectrum with precisely gaps. Moreover, we show that by an appropriate choice of the weights, the endpoint…

Burnings of trees and their homologies

Yuri Muranov, Anna Muranova

The problem of graph burning was firstly introduced as a model for different processes of social and network interactions. Recently, the authors of the present paper developed meth…

On the moments of the volume for random convex chains

Anna Gusakova, Anna Muranova

Let be the triangle in the plane with vertices , and . The convex hull of points , and independent random points uniformly di…

Homology of graph burnings

Yuri Muranov, Anna Muranova

In this paper we study graph burnings using methods of algebraic topology. We prove that the time function of a burning is a graph map to a path graph. Afterwards, we define a cate…

Recurrence and transience for non-Archimedean and directed graphs

Matthias Keller, Anna Muranova

We introduce the notion of recurrence and transience for graphs over non-Archimedean ordered field. To do so we relate these graphs to random walks of directed graphs over the real…

Power iteration for matrices with power series entries

Ragon Ebker, Anna Muranova, Max Schmidt

We prove the method of power iteration for matrices with at most finite entries from the Levi-Civita field under the assumption that there exists an eigenvalue with th…

Capacity of infinite graphs over non-Archimedean ordered fields

Florian Fischer, Matthias Keller, Anna Muranova +1

In this article we study the notion of capacity of a vertex for infinite graphs over non-Archimedean fields. In contrast to graphs over the real field monotone limits do not need t…

Dual Cheeger constant for weighted graphs over ordered fields

Anna Muranova

We consider a dual Cheeger constant for finite graphs with edge weights from an arbitrary real-closed ordered field. We obtain estimates of in terms of…

Discrete Laplace and transition operators over non-Archimedean ordered fields

Anna Muranova

We investigate properties of spectrum of normalized Laplacian for finite graphs over non-Archimedean ordered fields. We prove a Cheeger's inequality for first non-zero…

Networks with complex weights: Green function and power series

Anna Muranova, Wolfgang Woess

We introduce a Green function and analogues of other related kernels for finite and infinite networks whose edge weights are complex-valued admittances with positive real part. We…

Eigenvalues of the normalized complex Laplacian on finite electrical networks

Anna Muranova, Robert Schippa

The spectrum of the normalized complex Laplacian for electrical networks is analyzed. We show that eigenvalues lie in a larger region compared to the case of the real Laplacian. We…

The effective impedances of infinite ladder networks and Dirichlet problem on graphs

Anna Muranova

We calculate effective impedances of infinite - and - ladder networks as limits of effective impedances of finite network approximations, using a new method, which involves…

On the effective impedance of finite and infinite networks

Anna Muranova

In this paper we deal with the notion of the effective impedance of AC networks consisting of resistances, coils and capacitors. Mathematically such a network is a locally finite g…

Effective Impedance over Ordered Fields

Anna Muranova

In this paper, we study properties of effective impedance of finite electrical networks and calculate the effective impedance of a finite ladder network over an ordered field. More…

On the notion of effective impedance

Anna Muranova

It is known that electrical networks with resistors are related to the Laplace operator and random walk on weighted graphs. In this paper we consider more general electrical networ…
