Explicit and Effectively Symmetric Runge-Kutta Methods
Daniil Shmelev, Kurusch Ebrahimi-Fard, Nikolas Tapia +1
Symmetry is a key property of numerical methods. The geometric properties of symmetric schemes make them an attractive option for integrating Hamiltonian systems, whilst their abil…
Perturbative renormalisation of the model via generalized Wick maps
Nils Berglund, Tom Klose, Nikolas Tapia
We consider the perturbative renormalisation of the model from Euclidean Quantum Field Theory for any, possibly non-integer dimension . The so-called BPHZ renormalisat…
An introduction to tensors for path signatures
Jack Beda, Goncalo dos Reis, Nikolas Tapia
We present a fit-for-purpose introduction to tensors and their operations. It is envisaged to help the reader become acquainted with its underpinning concepts for the study of path…
