Two sequences of fully-nonlinear evolution equations and their symmetry properties

Marianna Euler, Norbert Euler

We obtain the complete Lie point symmetry algebras of two sequences of odd-order evolution equations. This includes equations that are fully-nonlinear, i.e. nonlinear in the highes…

From fully-nonlinear to semilinear evolution equations: two symmetry-integrable examples

Marianna Euler, Norbert Euler

In this paper we derive two examples of fully-nonlinear symmetry-integrable evolution equations with algebraic nonlinearities, namely one class of 3rd-order equations and a 5th-ord…

On differential equations invariant under a projective transformation group: integrability and reductions

Marianna Euler, Norbert Euler, Francesco Oliveri

We consider a projective transformation and establish the invariants for this transformation group up to order seven. We use the obtained invariants to construct a class of nonline…

On 2nd-order fully-nonlinear equations with links to 3rd-order fully-nonlinear equations

Marianna Euler, Norbert Euler

We derive the general conditions for fully-nonlinear symmetry-integrable second-order evolution equations and their first-order recursion operators. We then apply the established P…

The variation of Barnes and Bessel zeta functions

Clara L. Aldana, Klaus Kirsten, Julie Rowlett

We consider the variation of two fundamental types of zeta functions that arise in the study of both physical and analytical problems in geometric settings involving conical singul…

On the anti-quasi-steady-state conditions of enzyme kinetics

Justin Eilertsen, Santiago Schnell, Sebastian Walcher

Quasi-steady state reductions for the irreversible Michaelis--Menten reaction mechanism are of interest both from a theoretical and an experimental design perspective. A number of…
