As of my last knowledge update in October 2023, Marek Potemski does not appear to be a widely recognized figure in public knowledge or notable events. It's possible he may be known in a specific niche, profession, or region that is not covered by mainstream sources.

The limit of a function is a fundamental concept in calculus and mathematical analysis that describes the behavior of a function as its input approaches a certain value. Essentially, the limit helps us understand what value a function approaches as the input gets closer to a specified point, which may or may not be within the domain of the function.

The term "list of limits" can refer to several different contexts depending on the area of study or application. Here are some interpretations: 1. **Mathematics (Calculus)**: In the context of calculus, a list of limits refers to specific limit values for different functions or sequences as they approach a particular point. For example, some commonly evaluated limits might involve trigonometric functions, polynomial functions, or exponential functions.

Pierre Baruch could refer to various subjects, but it's not a widely recognized name or concept in popular culture, history, or current events as of my last knowledge update in October 2023. He may be a figure associated with a specific profession or context, potentially in academia, business, or another field.

Pierre Léna is a French astrophysicist notable for his contributions to the field of astronomy and his work in the development of scientific education and outreach.

Thomas-François Dalibard (born 15 November 1704 in Paris – died 12 January 1770 in Paris) was a French physicist notable for his work in the field of electricity. He is best known for his experiments in 1752 that involved lightning and demonstrated that lightning was a form of electrical discharge. Dalibard conducted experiments on the conduction of electricity using a lightning rod, which he had developed based on the theories suggested by Benjamin Franklin.

The Abel equation is a type of integral equation named after the Norwegian mathematician Niels Henrik Abel. It is typically expressed in the following form: \[ \frac{dy}{dx} = -f(y) \] where \( f(y) \) is a function of \( y \). The equation is often studied in the context of its relationship to certain integral representations, and it can also be transformed into different forms that may be more amenable to analysis.
