SPEAKER = Raluca Balan

ABSTRACT = In this talk we will introduce the basic elements of Ito's theory for the study of stochastic differential equations driven by Brownian motion. Then, we will sketch the basic ideas of the theory of stochastic partial differential equations (SPDEs) with Gaussian white noise, by focusing on the heat and wave equations.

ABSTRACT = Rank-based sampling (RBS) designs are alternatives to simple random sampling that can sometimes offer large improvements in precision for estimating population parameters such as the mean, quantiles, etc. The original idea was proposed in connection with estimating the mean pasture and forage yields in a paper by McIntyre (1952).

Algebra Seminar

SPEAKER = Ugo Bruzzo

UNIV = SISSA (Italy)

ABSTRACT = A classical result states that the very general surface of degree d larger than three in P3 has Picard number 1, and that the locus of surfaces of degree d with Picard number greater than 1 has codimension at least d-3.

Moreover, the lower bound is reached by the families of surfaces which contain a line. In this talk I will show how, under suitable assumptions, this can be  generalized to surfaces in (normal) projective simplicial toric 3-folds.

Joint work with Antonella Grassi.

Analysis Seminar

SPEAKER: Josel Cioppa (N/A)             ABSTRACT: A well known method for calculating polynomial integrals over the classical matrix groups and their quantum analogues, due to B. Collins and P. Sniady, is known as Weingarten calculus. In this talk, we will discuss an alternative method which, while similar in spirit to Weingarten calculus, allows for closed formulas for integrating over the first k rows of a matrix group (for k less than the size of the group). Cheers,

SPEAKER: Nevena Francetic (Monash University)

ABSTRACT:The famous Bruck-Ryser-Chowla theorem gives necessary conditions for the existence of symmetric designs. Here we present an adaptation of this famous theorem on the existence of symmetric pair coverings which have a 2-regular excess. In particular, we apply the Hasse-Minkowski invariant of rationally congruent matrices to study possible cycle types in the excess. Joint work with Sarada Herke and Daniel Horsley
