The title of the dissertation is "On Decoding Problems, Lattices and Generalized Concatenated Codes"

Reliable and efficient information transfer is one of the building blocks of today’s interconnected society. With more devices connected every day, the importance of reliable communication is constantly growing. Wireless networks are used everywhere and they are evolving at a rapid pace. The remarkable innovation and improvement in performance we have seen during the last decades is obviously a result of technological advances in many fields. However, none of this would be possible without information theory, and more specifically, coding theory.

One of the problems that coding theory deals with is: how can we achieve reliable and efficient communication over an unreliable channel. The answer is so-called error-correcting codes. In this thesis we study different types of error-correcting codes and so-called decoding algorithms for these codes. We improve known decoding algorithms for several classes of codes. This is important work, since there are many known good classes of error-correcting codes that cannot be used in practical applications due to impractical and/or slow decoding algorithms.

Summer 2021 Bridges conference

16. December 2019

Due to the covid-19 pandemic we will not be able to hold the Bridges Conference planned for Aalto University in August 2020. We will continue to process the papers for the Proceedings as planned, so authors of accepted papers will have their work officially recognized as reviewed and published. There will be a new paper cycle for the next Bridges Conference in the summer of 2021. More information can be found on the conference website.

Aalto Math & Arts in Shanghai Future Lab exhibition

Aalto Math & Arts in Shanghai Future Art Lab exhibition is a joint effort of three schools of Aalto University: School of Arts, Design and Architecture, School of Science and School of Engineering.

'The focus of our contribution in the exhibition is to introduce the interdisciplinary Math & Arts program, especially its underlying course Crystal Flowers in Halls of Mirrors: mathematics, arts and architecture related to activities of the audience', explains Kirsi Peltonen, Adjunct Professor in Mathematics from the Department of Mathematics and Systems Analysis Science.

Past, present & future – the elements of the exhibition

The exhibition concept is designed by Laura Isoniemi, designer and art pedagogue from the School of Arts, Design and Architecture.

'In the Future Lab exhibition we have three sections showcasing the development of Aalto Math & Arts program, the Past, Present and Future', Isoniemi says.

The Past section tells the story of the Aalto Math & Arts program through videos, posters, graphical info material, hands on educational models and ideas related to surface design.

The Present part continues the story by showing the latest course outcomes from the exhibition IN TRANSITION – Mathematics and Art at Espoo Cultural Centre in Finland via textiles and an interactive virtual exhibition realised by the School of Engineering.

The Future part communicates with different workshop outcomes how art and math can collaborate. It presents the pedagogical ideas implemented with students of Tongji-Huangpu School of Design & Innovation, teachers from different schools and universities in China and showcases a large-scale model designed by Taneli Luotoniemi. This sculpture, SPACE HUG, invites the visitor to join a non-stop installation process and build his/her own small-scale model from bamboo sticks.

The virtual exhibition combines conventional online content with panoramic images, illustrations, augmented reality and 3D scenes.

'By utilising the techniques from 3D geomatics, such as photogrammetry and laser scanning, the virtual exhibition allows the user to study the IN TRANSITION exhibition contents. It also creates a lasting digital footprint for the otherwise temporary event', says Juho-Pekka Virtanen, D.Sc. (Tech.) from the School of Engineering.

28th Nordic Congress of Mathematicians

Defence of dissertation in the field of Mathematics, Armando Gutierrez, M.Sc.22.11.2019

11. November 2019

The dissertation "Metric compactification of Banach spaces" contains a detailed overview of the construction of the metric compactification of arbitrary metric spaces followed by complete explicit descriptions of the metric compactification of classical Banach spaces in finite and infinite dimensions. Consequently, some ergodic and fixed point theorems are revisited.

Natural and social phenomena are often modeled by deterministic or random processes. These models can be mathematically described by a collection of mappings acting on certain spaces with a rich structure. Metric spaces are perfect environments where many mathematical models can be analyzed analytically and geometrically. In order to obtain precise knowledge of the model we also need certain topological properties. Compactness is a topological property that is needed in many areas of mathematics.

The metric compactification is the result of making a metric space into a dense subset of a compact space by adding a boundary at infinity. The elements of the metric compactification have functorial properties and, more importantly, define a weak topology on arbitrary metric spaces that gives a geometric interpretation of points escaping to infinity.

Explicit formulas for all the elements of the metric compactification of classical Banach spaces were presented in this dissertation. In addition, geometric proofs of certain ergodic and fixed point theorems were provided.
