Monotonicity in the parameter of the Mittag-Leffler function and determining the fractional exponent of the subdiffusion equation

Ravshan Ashurov, Ilyoskhuja Sulaymonov

In this paper, we prove the strict monotonicity in the parameter $I ¨ $ of the Mittag-Leffler functions $E_{I ¨} (- t^{I ¨} )$ and $t^{I ¨ - 1} E_{I ¨ , I ¨ } (- t^{I ¨} )$ . Then, these results are applied…

On fractional parabolic systems of vector order

Ravshan Ashurov, Ilyoskhuja Sulaymonov

The paper considers the Cauchy problem for the system of partial differential equations of fractional order $D_{t}^{B} U (t, x) + A (D) U (t, x) = H (t, x)$ . Here $U$ …

Determining the order of time and spatial fractional derivatives

Ravshan Ashurov, Ilyoskhuja Sulaymonov

The paper considers the initial-boundary value problem for equation $D^{I ¨} _{t} u (x, t) + (- I^)^{I ¨} u (x, t) = 0$ , $I ¨ \in (0, 1)$ , $I ¨ > 0$ , in an N-dimensional domain $I^c ◯$ with a homogeneous Dir…
