Regular Events Schedule
On Monday (10th), Professor Helena Verrill is running a meeting about maths art in the UG Workroom from 1700 to 1800. For more information, see the email from Professor Verrill.
Note: this event is run & organised by Professor Helena Verrill and is not affiliated with the Society.
On Wednesday (12th), we will be running Maths Café in the UG Workroom as always, from 1400 to 1600. As usual, we will be bringing some food for you to enjoy.
If you have any academic questions, our academic support officers (and many other attendees) will be happy to help. Also feel free to ask any questions about LaTeX.
The maths department are running a selection test for the IMC (International Mathematics Competition), also on Wednesday (12th) from 1400 to 1600. For more information, see this page.
Note: this event is run & organised by the maths department and is not affiliated with the Society.
On Thursday (13th), we have our regularly scheduled WMS Talk titled Almost full transversals in equi-n squares, with guest PhD speaker (and WMS Academic Support Officer 23/24) Teo Petrov, in MS.04, starting at 1800 until 1900.
Abstract:
In \(1975\), Stein made a wide generalisation of the Ryser-Brualdi-Stein conjecture on transversals in Latin squares, conjecturing that every equi-\(n\)-square (an \(n\times n\) array filled with \(n\) symbols where each symbol appears exactly \(n\) times) has a transversal of size \(n − 1\). That is, it should have a collection of \(n − 1\) entries that share no row, column, or symbol.
In \(2017\), Aharoni, Berger, Kotlar, and Ziv showed that equi-\(n\)-squares always have a transversal with size at least \(2n/3\).
In \(2019\), Pokrovskiy and Sudakov disproved Stein’s conjecture by constructing equi-\(n\)-squares without a transversal of size \(n − \frac{\log n}{42}\), but asked whether Stein’s conjecture is approximately true. I.e., does an equi-\(n\)-square always have a transversal with size \((1 − \mathrm{o}(1))n\)?
We answer this question in the positive. More specifically, we improve both known bounds, showing that there exist equi-\(n\)-squares with no transversal of size \(n − \Omega (\sqrt n)\) and that every equi-\(n\)-square contains \(n − n^{1−\Omega (1)}\) disjoint transversals of size \(n − n^{1−\Omega (1)}\).
As always, free pizza will be provided after the talk (suitable for all dietary requirements).
On Friday (14th), we are running Coffee and Cake, our weekly welfare event, from 1500 to 1600, in MB0.07 as a collaboration with the Warwick Statistics Society. Drop in to get a free hot drink and some free food, and relax with others in an informal and friendly environment.
