The Time-Periodic Cahn-Hilliard-Gurtin System on the Half Space as a Mixed-Order System with General Boundary Conditions

Guillaume Neuttiens, Jonas Sauer

A well-posedness and maximal regularity result for the time-periodic Cahn-Hilliard-Gurtin system in the half space is proved. For this purpose, we introduce a novel class of comple…

Limited-Range Multilinear Off-Diagonal Extrapolation and Weighted Transference Principle

Jonas Sauer

Multilinear extrapolation results are established in a limited-range, multilinear, and off-diagonal setting for mixed-norm Lebesgue spaces over -finite measure spaces. In…

FLASH-TB: Integrating Arc-Flags and Trip-Based Public Transit Routing

Ernestine Großmann, Jonas Sauer, Christian Schulz +2

We present FLASH-TB, a journey planning algorithm for public transit networks that combines Trip-Based Public Transit Routing (TB) with the Arc-Flags speedup technique. The basic i…

The Expiration Streaming Model: Diameter, -Center, Counting, Sampling, and Friends

Lotte Blank, Sergio Cabello, MohammadTaghi Hajiaghayi +5

An important thread in the study of data-stream algorithms focuses on settings where stream items are active only for a limited time. We introduce a new expiration model, where eac…

Schauder Estimates for Germs by Scaling

Jonas Sauer, Scott A. Smith

In this expository note, we show that the blow-up arguments of L. Simon adapt well to the corresponding Schauder theory of germs used in the study of singular SPDEs. We illustrate…
