Moser family

The Moser family refers to a collection of smooth, closed surfaces in four-dimensional space known for their distinctive properties in topology. These surfaces exemplify how certain complex shapes can be smoothly transformed into each other despite differences in their structure. They are important in understanding how higher-dimensional shapes can be manipulated and classified, revealing subtle distinctions in geometric and topological properties that are not apparent in three dimensions. The Moser family helps mathematicians explore the relationships and differences among complicated geometric objects in higher-dimensional spaces.
