“The category of cobordisms (Part II)”

We will continue to discuss the category of cobordisms, along with more examples.

Eric Boulter, Department of Pure Mathematics, University of Waterloo      "Vector Bundles on Non-Kähler Elliptic Fibre Bundles"      In this talk we will discuss non-Kähler complex surfaces which occur as elliptic fibre bundles, and some invariants of holomorphic vector bundles on these surfaces.  

Stanley Xiao, University of Toronto      "The density of power-free values of polynomials"      In this talk we show that any polynomial $F(x_1, \cdots, x_n)$ with integer coefficients and degree $d \geq 3$ and which satisfy basic necessary conditions take on the expected density of $k$-free values, provided that $k \geq \min\{d-1, 3d/4\}$. This generalizes results of Hooley and Browning, who showed the same result with $n = 1$. This is joint work with K.
