### Catherine Bruce - Dynamical Systems and Analysis Seminar Series

Catherine Bruce will be speaking at this research seminar, part of the Dynamical Systems and Analysis seminar series.

### Neil Thacker - Fundamental Issues Regarding Uncertainties in Artificial Neural Networks

(Zochonis Lecture Theatre D) Join us for this seminar by Neil Thacker (Manchester) as part of the Mathematics in the Life Sciences Series. Abstract: The problem of assessment of uncertainty in non-linear systems is re-visited and used to motivate an approach for estimation of parameter uncertainty based upon a Bayesian/Frequentist synthesis...

### Joni Teravainen (Oxford) - Higher order uniformity of the Möbius function

Abstract : In a recent work, Matomäki, Radziwill and Tao showed that the Möbius function is discorrelated with linear exponential phases on almost all short intervals. I will discuss joint work where we generalize this result to ''higher order phase functions'', so as a special case the Möbius function is shown not to correlate with polynom..

### Manchester Algebra Seminar - Robert Laugwitz - Braided Commutative Algebras over Quantized Enveloping Algebras

Speaker - Robert Laugwitz Title: Braided Commutative Algebras over Quantized Enveloping Algebras Algebras that are commutative in a braided tensor category appear in rational conformal field theory and in the study of extensions of vertex operator algebras. A construction of A. Davydov provides a way to associate to any algebra in a tenso..

### Franziska Jahnke - Characterizing NIP henselian valued fields

Franziska Jahnke joins us for the logic seminar. Abstract: (Joint work with Sylvy Anscombe) In this talk we characterize NIP henselian valued fields modulo the theory of their residue field. In particular, we show that every NIP henselian valued field satisfies some instance of the Ax-Kochen/Ersov principle. We then discuss several conseque..

### Steven Elsworth - Informal Applied Mathematics Seminar

The Informal Applied Mathematics seminar will continue with an hour long talk from Steven Elsworth. The talk will take place in Frank Adams 2 (next to the Alan Turing Building's kitchen), with complimentary hot drinks and biscuits from 2.45pm on the atrium bridge. Title and abstract for the talk can be found below. Steven Elsworth: Abstrac..

### Jana De Wiljes - Sequential learning via a combined reinforcement learning and data assimilation ansatz for decision support

Join us for this research seminar, part of the SQUIDS (Statistics, quantification of uncertainty, inverse problems and data science) seminar series. Abstract: In many applicational areas there is a need to determine a control variable that optimizes a prespecified objective. This problem is particularly challenging when knowledge on the under..

### Kyle Pratt (Oxford) - Number Theory Seminar Series

Join us for this research seminar, part of the Number Theory Seminar Series.

### Shreyas Mandre - Physical Applied Mathematics Seminar

Shreyas Mandre (Warwick) joins us for the Physical Applied Mathematics Series.

### Robbie Bancroft and Xiaobo Liu - Informal Applied Mathematics Seminar

The Informal Applied Mathematics seminar will continue with a double bill from Robbie Bancroft and Xiaobo Liu. Talks will take place in Frank Adams 2 (next to the Alan Turing Building's kitchen), with complimentary hot drinks and biscuits from 2.45pm on the atrium bridge. Title and abstracts for the talks can be found below. Robbie Bancroft:..
