#### Phil Herbert | MASDOC | The membrane mediated force on point attachments with application to a near spherical biomembrane

Abstract: We consider a hybrid model of a biomembrane with attached particles. The membrane is represented by a near spherical continuous surface, attached proteins are described by rigid bodies which are free to move tangentially and rotate in the axis normal to a reference point. As the standard energy for a membrane is highly non-linear, we consider a quadratic energy which may be shown to be an approximation of the Canham-Helfrich energy with a volume constraint and the deformations due to the attached proteins are imposed by point Dirichlet constraints. We show differentiability of the membrane energy with respect to parameterisation of these embedded particles and provide illustrative numerical examples.

#### Dom Brockington | MASDOC | Sticky Flows and KPZ Universality

Abstract: We shall introduce stochastic flows, and stochastic flows of kernels, before moving to the special case of sticky flows and their fluctuations. On the large deviation scale these fluctuations turn out to be Tracey-Widom GUE distributed, thus the sticky flows lie in the KPZ universality class.

#### Term 2: Tuesdays 2-3pm, B3.01

We're happy to announce and formally invite everyone to the SPAAM seminar series, a new forum where Maths & Stats PhD students as well as early researchers can present and discuss their work. The series is being organised by the SIAM Student Chapter here at Warwick.

Tea & Coffee? Yes – afterwards in the Maths common room

The seminar series aims to bring together CDT streams as well as straight PhD students across Mathematics and Statistics.

If you're interested in giving a talk, please let us know!
