Scientific Bulletin of Namangan State University


In this article, description of the generalized Abel integral equations was given and their visual solutions were found. Description of mixed fractional order integrals and derivatives which is taken multivariable function from other functionality was given because of using these explanations. Some properties of integrodifferential operators were learned in the article. In this case the theory of integral equations was widely used. The taken results were expressed like theorems and the proof was given completely.conductivity in narrow-gap semiconductors taking into account the thermal broadening of Landau levels. A new formula for the oscillation of the longitudinal conductivity in narrow-gap semiconductors has been obtained. The obtained theoretical results are compared with the experimental data for Bi2Se3.
