Abstract Elementary number theoretic properties of cyclotomic polynomials are a topic that has become very popular among olympiad mathematics and the discussions about and around several interesting olympiad problems. The purpose of this note is to give an introductory lesson about this issue and the structure behind it and to present some examples of how this knowledge can be used at olympiad ...

Although this lecture does not contain many offical Olympiad problems, the arguments which are used are all common elements of Olympiad problem solving. Some of these perhaps could have made nice Olympiad problems, if not for the fact that they were already well-known due to their importance in higher mathematics. Most of this is sourced from the excellent combinatorics course developed by Benn...

Since 2008 when we organised the First Australian Computation and Linguistic Olympiad (OzCLO), this high-school competition has become an annual event, with almost 800 participants across Australia in 2011. For the third time, we sent an Australian team to the International Linguistics Olympiad (ILO) and the team came back with one silver medal. In this talk, I will give an overview of OzCLO, f...

Dear Editor, Extracurricular activities for the gifted andtalented students in Iran derive from thebelief that students with high potentials areexpected to make great help for the healthcare of the community. One of these activitiesis holding medical science Olympiads. In theprevious meeting report about medical scienceOlympiad in year 2011, a unique experienceof Islamic Republic of Iran was re...

Many readers are familiar with the International Mathematical Olympiad (IMO), a pinnacle in the yearly calendar of mathematics competitions. Here we introduce its cousin in computer science, the International Olympiad in Informatics (IOI). The International Olympiad in Informatics is one of the newer Science Olympiads, beginning in 1989 in Bulgaria under the leadership of Petar Kenderov. In its...

The mathematical problems and their solutions of the Third International Students’ Olympiad in Cryptography NSUCRYPTO’2016 are presented. We consider mathematical problems related to the construction of algebraic immune vectorial Boolean functions and big Fermat numbers, problems about secrete sharing schemes and pseudorandom binary sequences, biometric cryptosystems and the blockchain technolo...

We present OLE, a dissemination activity of the EU Abu-MaTran project which aims to establish a linguistic Olympiad in Spain. We introduce the Linguistic Olympiads, our rationale and objectives for setting up OLE as well as our implementation plan. We foresee our work to be useful for other countries looking to start a Linguistic Olympiad.
