Workshop Speakers

1. Lorenzo Guerra, University of Rome Tor Vergata, France 

Lorenzo Guerra is currently a postdoctoral researcher at the University of Lille, affiliated to and funded by the OCHoTop project. He is working under the supervision of Prof. Benoit Fresse on the homotopy of (co)operads. He has also used some algebraic structures (mainly Hopf rings and variants) to study the cohomology of certain classes of spaces, among which there are the classifying spaces of finite Coxeter groups. Lorenzo Guerra obtained his PhD in Mathematics from the Scuola Normale Superiore in Pisa, Italy.

2. Huynh Mui, VNU University of Science, Hanoi, Vietnam 

Huỳnh Mùi was a student of Mathematics at the University of Tokyo in 1964 - 1974. He was well-known as the first person who grew up the Dickson algebra, the invariants of the polynomials under action of the general linear group, and gave these invariants a new living life as the image of the restriction in mod p cohomology of the symmetric group to a special maximal elementary abelian subgroup. Note that the modular invariants mentioned here include the exterior part of the odd degree elements for p an odd prime.
He also computed the modular invariants of the upper triangular matrix subgroup of the general linear group, these invariants become an effective tool if we use them together with the iterated Steenrod power map in the cohomology of wreath products.
Huỳnh Mùi was the starting person of the Vietnamese algebraic topology school.
In around 1990, he was interested in a different contribution to education. Recently, he turns out to be interested again in Algebraic Topology. Now, he comes back and gives talks and lectures on the cohomology of finite groups.

3. Jean Lannes, University of Paris 7, France 

Jean Lannes is a French mathematician, specializing in algebraic topology and homotopy theory. He completed his secondary studies at the Lycée Louis-le-Grand in Paris and graduated in 1966 from the École Normale Supérieure. He received his doctorate in 1975 from the University of Paris-Saclay (Paris 12). Lannes is known for his research on the homotopy theory of classifying spaces of groups. He proved in the mid-1980s the generalized Sullivan conjecture (which was also proven independently by Gunnar Carlsson and Haynes Miller). He was an invited speaker at the International Congress of Mathematicians (ICM) in Zurich in 1994. He is now professor emeritus of the University of Paris.

4. Nguyen Dang Ho Hai, University of Sciences, Hue University, Vietnam 

Nguyễn Đặng Hồ Hải is an Associate Professor at University of Sciences, Hue University, Vietnam. He obtained his PhD in Mathematics from the University of Paris 13 under the supervision of Lionel Schwartz, in 2010. His research interests include algebraic topology, especially unstable modules over the Steenrod algebra, and its relationships to group representation theory.

5. Nguyen Duc Nga, Phenikaa University, Vietnam 
Nguyen Duc Nga is a lecturer at Phenikaa University, Vietnam. Currently, he is a graduate student of Professor Nguyen Huu Viet Hung.

6. Sarah Whitehouse, University of Sheffield, England 

Sarah Whitehouse obtained her PhD from the University of Warwick in 1994, following a BSc (1990) and MSc (1991) also from Warwick. She spent several years in France, as a Marie Curie post-doctoral researcher at the Université Paris 13 and as a Maître de Conférences at Lens, before moving to Sheffield in 2002. In algebraic topology we use algebra to extract topological or geometric information about spaces. Among the standard tools used to carry out the translation from topology to algebra are generalised cohomology theories. Given such a theory there is an associated algebra of operations, carrying a wealth of structure and information. Prof Whitehouse is particularly interested in studying the structure and properties of these algebras.
