چکیده
Methods of determining, from small-variable asymptotic expansions, the characteristic exponents for variables tending to infinity are analyzed. The following methods considered: diff-log Padé summation, self-similar factor approximation, Borel and Borel–Leroy summation. Several typical problems treated. comparison results shows that all these provide close estimates large-variable exponents. reliable obtained when different summation compatible with each other.

Finite time blow up of solutions of the Kirchhoff-type equation with variable exponents
In this work, we investigate the following Kirchhoff-type equation with variable exponent nonlinearities u_{tt}-M(‖∇u‖²)△u+|u_{t}|^{p(x)-2}u_{t}=|u|^{q(x)-2}u. We proved the blow up of solutions in finite time by using modified energy functional method.
متن کاملVariable domains and variable relevance: interpreting phonetic exponents
Spoken language is a resource which is systematically deployed in the management of social interaction— its primary site of occurrence. The patterns and structures in language are emergent properties of and shaped by the exigencies and contingencies of social interaction. However, despite significant advances in modelling speech perception and understanding, and an increasing acknowledgment of ...
متن کاملPerturbed Subcritical Dirichlet Problems with Variable Exponents
We study a class of nonhomogeneous elliptic problems with Dirichlet boundary condition and involving the p(x)-Laplace operator and powertype nonlinear terms with variable exponent. The main results of this articles establish sufficient conditions for the existence of nontrivial weak solutions, in relationship with the values of certain real parameters. The proofs combine the Ekeland variational...
متن کاملAnisotropic Herz-morrey Spaces with Variable Exponents
In this paper, the authors introduce the anisotropic Herz-Morrey spaces with two variable exponents and obtain some properties of these spaces. Subsequently as an application, the authors give some boundedness on the anisotropic Herz-Morrey spaces with two variable exponents for a class of sublinear operators, which extend some known results.
متن کاملFast modular exponentiation of large numbers with large exponents
In many problems, modular exponentiation jxjm is a basic computation, often responsible for the overall time performance, as in some cryptosystems, since its implementation requires a large number of multiplications. It is known that jxjm 1⁄4 jxjbjuðmÞ jm for any x in 1⁄21;m 1 if m is prime; in this case the number of multiplications depends on uðmÞ instead of depending on b. It was also stated...
