The current research of fractional Sturm-Liouville boundary value problems focuses on the qualitative theory and numerical methods, much progress has been recently achieved in both directions. objective this paper is to explore a different route, namely, construction explicit asymptotic approximations for solutions. As study case, we consider problem with left right Riemann-Liouville derivative...

In this paper, we present a reliable framework to solve the initial and boundary value problems of Bratu-type which are widely applicable in fuel ignition of the combustion theory and heat transfer. The algorithm rests mainly on a relatively new technique, the variational iteration method. Several examples are given to confirm the efficiency and the accuracy of the proposed algorithm.

We construct a four-parameter family of Markov processes on infinite Gelfand-Tsetlin schemes that preserve the class of central (Gibbs) measures. Any process in the family induces a Feller Markov process on the infinite-dimensional boundary of the Gelfand-Tsetlin graph or, equivalently, the space of extreme characters of the infinite-dimensional unitary group U(∞). The process has a unique inva...

Abstract We compute projective dimension of translated simple modules in the regular block Bernstein–Gelfand–Gelfand category $\mathcal{O}$ terms Kazhdan–Lusztig combinatorics. This allows us to determine which projectives can appear at last step a minimal resolution for module, confirming conjecture by Johan Kåhrström. also derive some inequalities, Lusztig’s $\textbf{a}$-function, possible de...

The Harish-Chandra homomorphism is due to [Harish-Chandra 1951]. Attention to universal modules with highest weights is in ]Harish-Chandra 1951], [Cartier 1955], as well as [Verma 1968], [BernsteinGelfand-Gelfand 1971a], [Bernstein-Gelfand-Gelfand 1971b], [Bernstein-Gelfand-Gelfand 1975]. See also [Jantzen 1979]. [1] We treat sl(2) in as simple a style as possible, to highlight ideas. Then sl(3...
