When the heat equation and wave equation are approximated by ut = −Ku and utt = −Ku (discrete in space), the solution operators involve e−Kt, √K, cos(√Kt), and sinc( √ Kt). We compute these four matrices and find accurate approximations with a variety of boundary conditions. The second difference matrix K is Toeplitz (shift-invariant) for Dirichlet boundary conditions, but we show why e−Kt also...
The Hankel transform of an integer sequence (an) is defined as a sequence formed by the determinants of the matrices An, where An is the upper-left submatrix of size n× n of the Hankel matrix A = a0 a1 a2 a3 · · · a1 a2 a3 a4 · · · a2 a3 a4 a5 · · · .. .. .. .. . . . . In this talk, methods in deriving the Hankel transform of Bell and other Bell-type numbers will be discussed, particu...

the present dissertation aims to investigate four-word lexical bundles in applied linguistics research articles by iranian and internationally-published writers. the aims of this study are two-fold: first of all, attempts have been made to create a comprehensive list of the most commonly used four-word lexical bundles categorized by their type and token frequency, their structural characteristi...
Smith normal form evaluations found by Bessenrodt and Stanley for some Hankel matrices of q-Catalan numbers are proven in two ways. One argument generalizes the Bessenrodt–Stanley results for the Smith normal form of a certain multivariate matrix that refines one studied by Berlekamp, Carlitz, Roselle, and Scoville. The second argument, which uses orthogonal polynomials, generalizes to a number...
The main goal of this investigation is to obtain sharp upper bounds for Fekete-Szegö functional and the third Hankel determinant a certain subclass SL?u,v,? holomorphic functions defined by Carlson-Shaffer operator in unit disk. Finally, some special values parameters, several corollaries were presented.
In this paper, we investigate the sharp bounds of second Hankel determinant Logarithmic coefficients for starlike and convex functions with respect to symmetric points in open unit disk.
In this paper, we mainly study the order of q-starlikeness well-known basic hypergeometric function. addition, discuss Bieberbach-type problem and second Hankel determinant for a generalized class starlike functions.
