This article continues the analysis of the class of fractionally differentiable functions. We complete the main result of [4] that characterises the class of fractionally differentiable functions in terms of the pointwise convergence of certain improper integrals containing these functions. Our aim is to present an example, which shows that in order to obtain all fractionally differentiable functions, one may not replace the conditional convergence of those integrals by their absolute convergence.

The main objective of this study is to test the convergence of income per capita in APT countries through three models: absolute convergence, conditional convergence and sigma convergence. Regression analysis of panel data from 13 APT countries during the period of 2001-2014 is used to analysed to study problem. In absolute convergence model, the growth of real GDP per capita and initial real GDP are used as the variables, meanwhile, 8 variables such as the growth of real GPD per capita, initial real GDP per capita, labor force ratio, value added in agricultural sector, value added in industrial sector, terms of trade, foreign direct investment and internet users ratio are analyzed in conditional convergence model. According to the Solow model, the economies of the countries will converge in which the growth of income per capita of developing countries will be higher than those of developed countries. The economies will be convergent if the countries tend to move to a similar steady state resulting in smaller gap between the countries. Based on the results of absolute convergence and conditional convergence models, APT countries is converging with the rate of 2% and 2.2%. This is consistent with the results of sigma convergence model that shows a declining trend in the dispersion of real GDP per capita in APT regions. The growth of real GDP per capita is influenced by initial GDP per capita, labor force ratio, value added in agricultural sector, value added in industrial sector, terms of trade, foreign direct investment and internet users ratio. Developed countries such as Singapore, Brunei Darussalam and South Korea experience the impact of high real GDP per capita growth. On the contrary, Indonesia, Laos, Vietnam and The Phillipines undergo the impact of low GDP per capita growth.

We formulate a necessary condition for functionals with Lagrangians depending on fractional derivatives of differentiable functions to possess an extremum. The Euler-Lagrange equation we obtained generalizes previously known results in the literature and enables us to construct simple Lagrangians for nonlinear systems. As examples of application, we obtain Lagrangians for some chaotic dynamical systems.

In this article, we established a wide range of fractional mean-type integral inequalities for notable Hilfer fractional derivative using twice differentiable convex and $s$-convex functions for $s\in(0,1]$ with related identities. Also the results for Caputo fractional derivatives are derived as a special case of our general results.

Dengan menggunakan data panel 505 kabupaten/kota di Indonesia selama periode pelaksanaan desentralisasi dari tahun 2001-2017, penelitian ini bertujuan untuk menguji tentang indikasi konvergensi perekonomian antar daerah di Indonesia dan untuk mengetahui pengaruh kebijakan desentralisasi fiskal terhadap konvergensi pendapatan perkapita antar daerah di Indonesia. Indikator desentralisasi fiskal menggunakan indikator pendapatan dan indikator belanja daerah. Indikator pendapatan daerah terdiri dari pendapatatan asli daerah, dana bagi hasil, dan dana transfer. Indikator belanja daerah fokus pada belanja sektor pendidikan, sektor kesehatan, dan sektor infrastruktur. Menggunakan analisa konvergensi statis, penelitian ini menemukan bukti bahwa terjadi konvergensi pendapatan perkapita antar kabupaten/kota di Indonesia. Analisa konvergensi dinamis dengan model absolute convergence dan conditional convergence. Hasil estimasi model absolute convergence menunjukkan terjadinya konvergensi pendapatan perkapita antar kabupaten/kota di Indonesia dengan tingkat konvergensi sebesar 7 persen. Sedangkan hasil estimasi model conditional convergence menghasilkan tingkat konvergensi sebesar 19 persen ketika tenaga kerja, investasi, angka partisipasi pendidikan, dan indikator desentralisasi fiskal disertakan dalam model.
