# Unexpected hypersurfaces with multiple fat points

## TL;DR

This paper introduces the first known examples of unexpected hypersurfaces with multiple fat points, expanding the understanding of such phenomena by studying Fermat-type configurations in projective spaces.

## Contribution

It presents new examples of unexpected hypersurfaces with multiple fat points, a novel phenomenon not previously observed in the field.

## Key findings

- Existence of unexpected hypersurfaces with multiple fat points
- Construction of examples using Fermat-type configurations
- Extension of known phenomena to more complex point schemes

## Abstract

Starting with the ground-breaking work of Cook II, Harbourne, Migliore and Nagel, there has been a lot of interest in unexpected hypersurfaces. In the last couple of months a considerable number of new examples and new phenomena has been observed and reported on. All examples studied so far had just one fat point. In this note we introduce a new series of examples, which establishes for the first time the existence of unexpected hypersurfaces with multiple fat points. The key underlying idea is to study Fermat-type configurations of points in projective spaces.
