01 February 2013 - Laplace transform methods for parabolic problems with time-dependent coefficients

*Dongwoo Sheen - Seoul National University*

The Laplace transformation method has proven to be very efficient for dealing with parabolic problems whose coefficients are time-independent, and is easily parallelizable. However, it seems...

*Youngmok Jeon - Ajou University, Suwon*

We describe hybridized finite element methods for partial differential equations, which are based on constructing local solutions on each triangle of a triangulation and patching these local...

*Professor Gene Abrams - University of Colorado*

The rings studied by students in most first-year algebra courses turn out to have what's known as the "Invariant Basis Number" property: for every pair of positive integers m and n, if the free...

*Prof. Zung Dinh - Vietnam National University*

In recent decades, there has been increasing interest in solving numerical problems that involve functions depending on a large number d of variables. These problems arise from many applications in...

*Pierre L'Ecuyer - DIRO, Universite de Montreal, Canada*

We review the basic principles underlying the design of uniform random number generators, their quality requirements, their theoretical analysis, and their empirical testing. We explain why we prefer...

*Prof Pierre L'Ecuyer - Université de Montréal (Canada)*

Monte Carlo methods provide estimators whose standard error usually decreases at a slow rate dictated by the central limit theorem. In theory, there exist simulation estimators with zero variance, i....

*David Harvey - UNSW*

The accumulating remainder tree is an algorithmic tool discovered by Robert Gerbicz in 2011. I will explain how it works, and describe how it can be used to efficiently search for Wilson primes,...

*Len Scott - The University of Virginia*

In 1961 G.E. Wall conjectured that the number of maximal subgroups of a finite group is less than the order of the group. The conjecture holds for all finite solvable groups (proved by Wall himself...

*Prof David Harris - Monash University*

This paper considers testing the null hypothesis of temporal independence in a first order integer autoregressive (INAR) model for count data in which the distribution of the disturbances (the...

*Mircea Voineagu - UNSW*

I will discuss motivations and constructions of motivic cohomology (introduced by Voevodsky) of smooth schemes over a field of characteristic zero. Then I will present a construction of...
