On an ambiguity in the concept of partial and total derivatives in classical analysis
Ambiguity is shown in the context of the differential calculus of several variables and with the help of the language of category theory, a way to solve it in...
On metallicity distribution for planet-hosting stars
The study of stellar parameters of planet-hosting stars, such as metallicity and chemical abundances, help us to understand the theory of planet formation and...
