  1. Rational linear spaces on hypersurfaces over quasi-algebraically closed fields. (slides)

    • 2011-08-19: the Young Mathematicians Conference 2011
    • 2012-01-04: *the AMS Special Session on Arithmetic Geometry of the Joint Mathematics Meetings in Boston, MA

  2. Variant of a theorem by Erdős on the sum-of-proper-divisors function.
    • Version I (2012-05-29): Honours thesis defence
    • Version II (2012-06-17): Canadian Number Theory Association Meeting XII. There is an improvement of the main result.)
    • Version III (2012-07-27): Young Mathematicians Conference 2012. (The only differences between Version II and this version are the colour of the slides and the addition of background terminology. Red for Canada in Version II, Green for Dartmouth in Version III.)
    • Version IV (2012-12-18): West Coast Number Theory 2012. There is a major improvement of the main result.
    • *Version V (2013-01-11): AMS Special Session on the Covering of the Integers at the Joint Mathematics Meetings in San Diego. Now the ``factorial/exclamation mark'' joke gets a proper, `complete' citation! ;)
