The Mathematical Analysis and Applications Laboratory is a laboratory associated with the CNRS (UMR 7539). It is attached to the Institut Galilée, a component of the Sorbonne Paris Nord University, and to the Paris 8 University. The Lbo is also associated with several LaBeXs: SMP, INFLAMEX and MME-DII.

It includes approximately researchers and teacher-researchers (including ten CNRS researchers), 7 ITA and BIATSS staff, more than 50 doctoral students and it receives more than thirty foreign visitors and post-docs each year.

The main research themes currently being developed within the laboratory are as follows:
Arithmetic, algebraic geometry, number theory, category theory, algebraic topology, homotopy theory, representation theory, dynamic systems, ergodic theory, harmonic analysis, linear and nonlinear partial differential equations, microlocal analysis, mathematical physics, spectral theory, numerical analysis, probability and statistics, stochastic analysis, coding and cryptography, image processing.
