Abstract Set Theory
A visually engaging representation of abstract set theory concepts featuring Venn diagrams, intersecting sets, and union operations. The image should consist of colorful interconnected circles and ellipses with distinct borders and labeled sections, showcasing elements and their relationships. Mathematical symbols and notations should be incorporated to reflect the academic nature of set theory. The background should be simple and minimalistic, allowing the mathematical visuals to stand out prominently. No images of people should be included.
