#### Lewis Carroll in Numberland

###### Robin Wilson   [email] (Open University and Gresham College)

Abstract: If Charles Dodgson (Lewis Carroll) hadn’t written Alice’s Adventures in Wonderland and Through the Looking-Glass, he’d probably be remembered as a pioneer photographer – and also as a mathematician? But what mathematics was he interested in? – and how good was he? In this talk I summarize his mathematical life and works in the context of the world of Victorian Oxford – with particular reference to his work in Euclidean geometry, algebra, the theory of voting, and logic.  Robin Wilson is an Emeritus Professor of Pure Mathematics at the Open University, Emeritus Professor of Geometry at Gresham College, London, and a former Fellow of Keble College, Oxford University. He is currently a Visiting Professor at the London School of Economics. A former President of the British Society for the History of Mathematics, he has written and edited about 40 books on the history of mathematics, including 'Lewis Carroll in Numberland', and also on graph theory, including 'Introduction to Graph Theory' and 'Four Colours Suffice'. Involved with the popularization and communication of mathematics and its history, he has been awarded the Mathematical Association of America’s Lester Ford award and Pólya prize for his ‘outstanding expository writing’.

#### Zariski Tangent Space to the moduli of vector bundles on an algebraic curve II

###### Jin Hyung To   [email] (UIUC)

Abstract: We will find the Zariski tangent space to the moduli space of vector bundles. This is the quotient vector space of the Zariski tangent space to the Hilbert scheme. In particular, we find the Zariski tangent space to the Jacobian variety using deformations.

#### IGL Mid-Semester Meeting

Abstract: Come see what the IGL research groups have been working on this semester! 5:15-6:15 followed by pizza.
