# Analysis Seminar: Andrei Osipov (Yale) "On the evaluation of sums of periodic Gaussians"

12:00pm to 1:00pm

## Location:

Ross 70

Title:

On the evaluation of sums of periodic Gaussians

Abstract:

Discrete sums of the form

$\sum_{k=1}^N q_k \cdot \exp\left( -\frac{t – s_k}{2 \cdot \sigma^2} \right)$

where $\sigma>0$ and $q_1, \dots, q_N$ are real numbers and

$s_1, \dots, s_N$ and $t$ are vectors in $R^d$,

are frequently encountered in numerical computations across a variety of fields.
