School overview:
In graph theory, the spectra of matrices associated with a graph are widely used to characterize its properties and to extract structural information. There are several graph matrix representations such as the adjacency matrix, combinatorial Laplacian, normalized Laplacian and signless Laplacian. Spectral graph theory has also many applications in other scientific fields such as chemistry, theoretical physics, and quantum mechanics, but we will focus here to applications in computer science. One of the oldest applications of graph spectra in Computer Science is related to expander graphs. It is known that graphs having a large eigenvalue gap possess very good expansion and connectivity properties. This property is used in the design of interconnection networks with good algorithmic properties. Another application of graph spectra is in the area of graph partitioning. This problem naturally arises in e.g. numerical simulations, VLSI design, or data mining. On one hand, the eigenvalues of the corresponding graph are used to derive lower and upper bounds on the quality of partitioning algorithms. On the other hand, the eigenvector corresponding to the second eigenvalue of Laplacian matrix can be used to partition the graph into two (equal) parts such that the number of edges separating the two parts is small.
Eigenvalues of graphs are also used to capture the convergence of certain (diffusion based) load balancing algorithms, whose schemes can be described by iterative methods based on certain matrices associated with the underlying network topology. The eigenvalues of these matrices are closely related to the Laplacian eigenvalues of the corresponding graph, and then we are able to apply known techniques from linear algebra to bound the running time of these load balancing algorithms. A somewhat related process to diffusion load balancing is the PageRank algorithm of Google. Of particular importance are, again, linear algebraic methods. Spectral retrieval is a popular approach to rank Web pages among large collections of documents. The basic scheme assumes that the documents as well as the queries are represented by high dimensional vectors. Then, these are projected to a low dimensional eigenspace, which is computed from the document vectors. The rank of the documents is obtained by their similarity to the query in the eigenspace.
In the last years, a relationship between graph spectra and certain information dissemination algorithms has been discovered. It has been shown that the second eigenvalue is well suited to capture the expected running time of so called rumor spreading algorithms in graphs with large eigenvalue gap. Furthermore, there is a close connection between the cover time of random walks and rumor spreading.
The spectrum of a graph can also be used to describe the spread of certain epidemic models in networks. Whenever the question is, how fast the disease reaches all persons, the problem reduces to randomized rumor spreading. However, in most of these studies, spreaders are only active in a certain time window, and the question of interest is, whether on certain networks modeling personal contacts an epidemic outbreak occurs.
The aim of proposed summer school is to introduce students to the theoretical properties of different graph spectra and to explain in detail the abovementioned applications, thereby creating a comprehensive foundation for students’ introduction to research in this important field of graph theory.

4. Lecturers and course material (it is expected that except attending the course lectures the students can attend more than 60 talks) :

Course Title: Coding Theory---An Advanced Introduction

Duration: 10 h

Description: Shannon's famous channel coding theorem asserts that information can be reliably transmitted over noisy communication channels at any rate below channel capacity. Algebraic coding theory employs concepts from abstract algebra for the actual construction of error-correcting codes for reliable communication. The course provides an introduction at the Ph.D. level to the most important classes of algebraic codes and their decoding.

Major Topics:
1) Basic terminology
2) Bounds for codes
3) Linear codes
4) MacWilliams identities
5) Cyclic codes
6) CRC codes
7) Polynomial codes
8) Decoding of cyclic codes
9) List decoding of Reed-Solomon codes.

Lecturer: Prof. Thomas Honold – Munich Technical University

Course Title: Linear Codes and Finite Geometries

Duration: 10 h

Description: It is known that linear codes over finite fields are equivalent to arcs with certain parameters in the projective geometries. In this course we consider some important problems about objects in finite geometry and their relevance to optimization problems in coding theory.

Major Topics:
1) Arcs and blocking sets in PG(t,q)
2) Ovals and hyperovals
3) Maximal arcs. The maximal arc conjecture.
4) Caps
5) The Griesmer bound
