Theoretical problems refer to challenges or questions that arise within a specific field of study, often requiring abstract thinking and conceptual analysis. These problems may not have practical solutions but are essential for advancing knowledge and understanding. They can be found in various disciplines, including mathematics, physics, and philosophy. In mathematics, for example, theoretical problems can involve proving theorems or exploring the implications of certain axioms. In physics, they might relate to understanding fundamental forces or the nature of the universe. Addressing these problems often leads to new theories and insights, driving progress in science and academia.
