4th year projects 2021/22 (more information via email to Stefan Adams):

  • Large deviations for random walks or Brownian motions (deviation from the law of large numbers & connection with entropy): several projects linked to MA4L3; MA3K0; MA4F7 ;MA4F7; MA4A7; MA4L2; MA482
  • Large deviations for random integer sequences and their minimisers - an application from MA4L3.
  • Large deviations for random partitions and the scaled shape limits of Young tableaux - an application from MA4L3.
  • Neural networks and machine learning
  • Application in mathematical finance - martingales; Large deviations; Wasserstein gradient flows
  • High-Dimensional probability - MA3K0 - concentration inequalities

MSc projects (list of examples - more via discussion with Stefan Adams):

(1.) Large deviations for integrated random walks (with different applications)

(2.) Scalings limits for cycle distributions (non-standard CLTs)

(3.) Concentration inequalities - MA3K0

(4.) Gaussian free field (discrete) and its scaling to the continuous version

(5.) Permanental point processes

Ph.D. projects (list of examples of possible directions/questions):

(I) Renormalisation group theory & regularity structure (nonlinear SPDEs) via infinite-dimensional Laplace integral methods

(II) Large deviations for multi-dimensional random walks under pinning constraints and their multiple stochastic limits

(III) Gaussian Free Field (real and complex) and loop measures

(IV) Interacting Brownian motions and applications

(V) Concentration inequalities for dependent random variables - applications in data science and machine learning
