Subject: This week's colloquium, Tuesday 28 March, Raul Hindov

Dear all,

Details for this week's colloquium follow.

***

Speaker: Raul Hindov, Lund University, Sweden

Title: Factoring integers with Ford circles and Dirichlet's approximation with Short circles

Abstract: We describe a geometric method developed by Lester R Ford in the 1930s to visualize the calculation of continued fractions, and we use the technique to give an alternative geometric proof of a lemma that is the basis for an integer factorization method that uses continued fractions. Further, we prove a corollary that reduces the factoring problem by a factor 2. Short circles, which are closely related to Ford circles, are employed to present a geometric proof of Dirichlet's approximation theorem.

Time, date, location: 15.30, Tuesday 28 March, Alan Turing 306, tea and coffee in common area 15.00

Raul is a (mature) student who wrote a dissertation on a subject I have worked on. He has a small scholarship to visit us for the week, from Sweden. He'll be located in the visitors' room. Please help to make him welcome!

Best wishes,

Ian
