Working together: end-of-term mathematical board games
Abstract
Would you like to meet some of your fellow students, and some graduate students and postdocs, in an informal and relaxed atmosphere, while building your communication skills? In this Friday@2 session, you'll be able to play a selection of board games, meet new people, and practise working together. What better way to spend the final Friday afternoon of term?! We'll play the games in the south Mezzanine area of the Andrew Wiles Building, outside L3.
Dissertation: presenting a thesis
Abstract
This session is particularly aimed at fourth-year and OMMS students who are completing a dissertation this year. The talk will be given by Dr Richard Earl who chairs Projects Committee. For many of you this will be the first time you have written such an extended piece on mathematics. The talk will include advice on planning a timetable, managing the workload, presenting mathematics, structuring the dissertation and creating a narrative, providing references and avoiding plagiarism.
Mathematics: the past, present and future - “Infecting by Numbers”
Abstract
Outbreaks and epidemics from Ebola to influenza and measles are often in the news. Statistical analysis and modelling are frequently used to understand the transmission dynamics of epidemics as well as to inform and evaluate control measures, with real-time analysis being the most challenging but potentially most impactful. Examples will be drawn from diseases affecting both humans and animals.
What's it like to do a DPhil/research?
Abstract
This week's Fridays@2 will be a panel discussion focusing on what it is like to pursue a research degree. The panel will share their thoughts and experiences in a question-and-answer session, discussing some of the practicalities of being a postgraduate student, and where a research degree might lead afterwards. Participants include:
Jono Chetwynd-Diggle (Smith Institute)
Victoria Patel (PDE CDT, Mathematical Institute)
Robin Thompson (Christ Church)
Rosemary Walmsley (DPhil student Health Economics Research Centre, Oxford)
Banish imposter feelings (and trust you belong!)
Abstract
How can it be that so many clever, competent and capable people can feel that they are just one step away from being exposed as a complete fraud? Despite evidence that they are performing well they can still have that lurking fear that at any moment someone is going to tap them on the shoulder and say "We need to have a chat". If you've ever felt like this, or you feel like this right now, then this Friday@2 session might be of interest to you. We'll explore what "Imposter Feelings" are, why we get them and steps you can start to take to help yourself and others. This event is likely to be of interest to undergraduates and MSc students at all stages.
Where does collaborating end and plagiarising begin?
Abstract
Despite the stereotype of the lone genius working by themselves, most professional mathematicians collaborate with others. But when you're learning maths as a student, is it OK to work with other people, or is that cheating? And if you're not used to collaborating with others, then you might feel shy about discussing your ideas when you're not confident about them. In this session, we'll explore ways in which you can get the most out of collaborations with your fellow students, whilst avoiding inadvertently passing off other people's work as your own. This session will be suitable for undergraduate and MSc students at any stage of their degree who would like to increase their confidence in collaboration. Please bring a pen or pencil!
What does a good maths solution look like?
Abstract
In this interactive workshop, we'll discuss what mathematicians are looking for in written solutions. How can you set out your ideas clearly, and what are the standard mathematical conventions? Please bring a pen or pencil!
This session is likely to be most relevant for first-year undergraduates, but all are welcome.
Making the most of the intercollegiate classes
Abstract
What should you expect in intercollegiate classes? What can you do to get the most out of them? In this session, experienced class tutors will share their thoughts, and a current student will offer tips and advice based on their experience.
All undergraduate and masters students welcome, especially Part B and MSc students attending intercollegiate classes. (Students who attended the Part C/OMMS induction event will find significant overlap between the advice offered there and this session!)
Characterisation of quasirandom permutations by a pattern sum
We say that a sequence $\{\Pi_i\}$ of permutations is quasirandom if, for each $k\geq 2$ and each $\sigma\in S_k$, the probability that a uniformly chosen $k$-set of entries of $\Pi_i$ induces $\sigma$ tends to $1/k!$ as $i$ tends to infinity. It is known that a much weaker condition already forces $\{\Pi_i\}$ to be quasirandom; namely, if the above property holds for all $\sigma\in S_4$. We further weaken this condition by exhibiting sets $S\subseteq S_4$, such that if a randomly chosen $k$-set of entries of $\Pi_i$ induces an element of $S$ with probability tending to $|S|/24$, then $\{\Pi_i\}$ is quasirandom. Moreover, we are able to completely characterise the sets $S$ with this property. In particular, there are exactly ten such sets, the smallest of which has cardinality eight.
