</span><span
style="font-size:11pt;font-family:Arial,sans-serif;font-variant-numeric:normal;font-variant-east-asian:normal;font-variant-alternates:normal;vertical-align:baseline">Quantifying
spatial interactions in multi-species spatial biology
datasets is crucial for understanding the underlying
biology, for example in multicellular spatial data arising
from tumor tissue samples. Existing approaches to quantify
such interactions from spatial statistics, network
science, and topological data analysis (TDA) are largely
restricted to studying pairwise interactions between
individual species. Higher-order spatial interactions are
captured through their induced pairwise interactions,
which can lead to an incomplete picture of the biological
context. The present work addresses this limitation, using
recent advances in TDA to develop a new framework that
quantifies higher-order spatial interactions involving
multiple species directly, and validates such framework on
synthetic and empirical spatial biology datasets.</span></p>
