A polygon with holes, often referred to as a "polygonal region" or "complex polygon," is a type of geometric figure that consists of a main outer polygon and one or more inner polygons (the holes) that are not part of the area of the main polygon. Here are some key aspects of polygons with holes: 1. **Structure**: The outer boundary is a simple polygon, while the holes are usually also simple polygons that are entirely enclosed by the outer boundary.

The Poncelet–Steiner theorem is a result in projective geometry that pertains to the construction of geometric figures using a limited set of tools: typically a compass and a straightedge.

Cyclone Martin was a significant tropical cyclone that occurred in the southwest Indian Ocean during the 1999 cyclone season. It formed in early March 1999 and was notable for impacting several islands in the region, including Madagascar and Mauritius. It reached a peak intensity of around 120 km/h (75 mph), classified as a moderate tropical storm on the Saffir-Simpson scale.

Raman Parimala is a prominent Indian mathematician known for her contributions to algebraic geometry and commutative algebra. She has made significant advancements in the study of homogeneous spaces, and her work has implications for various areas in mathematics, particularly in the context of algebraic groups and their representations. In addition to her research contributions, Parimala has been involved in mathematical education and has played a role in promoting mathematics among women and underrepresented groups in the field.

Reinhold Baer (1913-2005) was a German-American mathematician known for his contributions to algebra and topology.
