The Pure and Applied Mathematical Analysis Research group (PAMAR) is a community of mathematicians and historians of mathematics at the Department of Mathematical Sciences who are researching within a range of domains of mathematics and history of mathematics. The PAMAR group comprises ten researchers who developed distinctive research profiles via participation in conferences, external visits, and joint research. The quality of research conducted by the group members has been acknowledged both at the national level and internationally. 

PAMAR is organized in three subgroups:

Functional analysis

Research topics: geometry of Banach spaces, approximation properties, massiveness properties, ideal structures, diameter 2 properties in Banach spaces

Differential Equations and Dynamical Systems 

Research topics: ergodic Ramsey theory, combinatorial number theory, stochastic analysis (rough paths, fluid equations,and Malliavin calculus nonlinear stochastic partial differential equations, local and global well-posedness of dispersive equations for rough initial data), differential equations (asymptotic behaviour of solutions to nonlinear differential and functional differential equations, mathematical modelling)
