    How do you choose a random finite abelian group? A d x d integer matrix M gives a linear map from Z^d to Z^d. The cokernel of M is Z^d/Im(M). If det(M) is nonzero, then the cokernel is a finite abelian group of order det(M) and rank at most d. What do these groups ‘look like’? How often are they cyclic? What can we say about their p-...

    I will present some recent results on equidistributive properties of toral eigenfunctions. Only a  minimal knowledge of Fourier analysis is required to follow all the details of this talk.

    The celebrated Alexandrov-Bakelman-Pucci Maximum Principle (often abbreviated as ABP estimate) is a pointwise estimate for solutions of elliptic equations, which was introduced in the 1960s. It was motivated by beautiful geometric ideas and has been a fundamental tool in the study of non-divergent PDEs. More recently, this...

    In this talk, we shall give a mathematical setting of the Random Backpropogation  (RBP) method in unsupervised machine learning. When there is no hidden layer in the neural network, the method degenerates to the usual least square method. When there are multiple hidden layers, we can formulate the learning procedure as a system of nonlinear...
