Description de l'emploi

General information Reference : UMR6629-MARGOL-001

Workplace : NANTES

Date of publication : Wednesday, May 05, 2021

Type of Contract : FTC Scientist
Contract
Period : 18 months

Expected date of employment : 1 September 2021

Proportion of work : Full time

Remuneration : Between 2650€ and 3800€ (monthly, before taxes), depending on experience.

Desired level of education : PhD

Experience required : Indifferent


Missions
The project PSyCo (Projective SYmplectic COnfigurations; Étoile Montante, financed by the Région Pays de la Loire; PI: Marco Golla) aims at better understanding configurations of (possibly singular) symplectic curves in the complex projective plane, especially in comparison with their algebro-geometric counterparts. The project lies at the crossroads between low-dimensional topology, symplectic geometry, and (complex) algebraic geometry.
The successful applicant will be part of the group TGA (Topology, Geometry, and Algebra) of the Mathematics Department in Nantes, which has specialists in all three areas.

Activities
The postdoc will work with the PI on porting algebro-geometric techniques for the study of singular curves and configurations (especially in rational surfaces) to the symplectic and topological context. This is in continuity with the PI's work on rational cuspidal curves. Possible new lines of investigation include Alexander polynomials (Libgober), the log minimal model program (Koras, Palka), and the log BMY inequality (Orevkov).

Skills
The ideal candidate will have a PhD in algebraic geometry, symplectic geometry, or low-dimensional topology. Some knowledge of complex algebraic geometry (especially of curves and surfaces) and some familiarity with differential topology are required.

Work Context
The Mathematics Department in Nantes (Laboratoire de Mathématique Jean Leray, LMJL) is a research unit for the University of Nantes and the CNRS, and is partner with the École Centrale de Nantes. It employs roughly 100 people (of which 26 full professors, 29 assistant professors, 2 directors of research, 6 researchers, 4 postdocs, and 31 PhD students) and comprises five research groups. The TGA (Topology, Geometry, and Algebra) group comprises 13 permanent members, of which 7 work on topics closely related to the project PSyCo.

Description de l'emploi

Postdoctoral position : Analysis and numerical methods for plasma sheath models

The MUFFIN(MUltiscale and treFFtz for numerIcal traNsport ) ANR project aims at making progress in the numerical simulation of multidimensional kinetic equations. A part of the project is concerned with modeling and accurate numerical simulation of plasma sheaths. Plasma sheaths are non neutral boundary layers that develop when a plasma is in contact with a metallic wall [3, 5, 1]. Their modeling is a challenge and the development of specific numerical methods for their accurate simulations is a bottleneck for global plasmas simulations (specifically in the context of the ITER project [4]). We are seeking a dynamic PhD graduate in applied mathematics, with a tropism for numerical analysis and scientific computing for PDEs. The project will require both theoretical studies and implementation of numerical methods.
Depending on the preference and/or expertise of the applicant, several work leads are possible:

  •  The construction of stationary plasma sheaths in cylindrical geometry.
  •  A linear stability study of plasma sheaths.
  •  The development of compatible semi-Lagrangian schemes for the Vlasov-Ampere equations that preserve a discrete Gauss Law [2].

Location: Laboratoire de Mathématiques Jean Leray, Université de Nantes.
Grant: ANR MUFFIN project.
Advisors: Mehdi BADSI, Christophe BERTHON and Anaïs CRESTETTO
Beginning: September 2021 or October 2021.
Duration: 12 months.

The deadline for applying is June 1rst 2021.
