On a New Approach by Modified (P; Q)-Szasz-Mirakyan Operators
(Etamaths Publ., 2021)In this paper, we introduce a new type of (p; q) exponential function with some properties and a modified (p; q)-Szasz-Mirakyan operators by virtue of this function by investigating approximation properties. We obtain ... -
On the Grand Wiener Amalgam Spaces
(Rocky Mt Math Consortium, 2020)We define the grand Wiener amalgam space by using the classical Wiener amalgam space and the generalized grand Lebesgue space. Moreover we study the inclusions between these spaces and some applications. Finally we prove ... -

(Elsevier, 2014)We prove that the outer automorphism group of a free group of countably infinite rank is complete. -
On the weighted variable exponent amalgam space W(L-P(X) , L-M(Q))
(Elsevier, 2014)In [4], a new family W(L-p(x), L-m(q))of Wiener amalgam spaces was defined and investigated some properties of these spaces, where local component is a variable exponent Lebesgue space L-p(x) (R) and the global component ... -
Phase-dependent interference fringes in the wavelenght scaling of harmonic efficiency
(American Physical Society, 2014)We describe phase-dependent wavelength scaling of high-order harmonic generation efficiency driven by ultra-short laser fields in the mid-infrared. We employ both numerical solution of the time-dependent Schr¨odinger ... -
Pippard relations for cubic gauche nitrogen
(2016)The Pippard relations (CP vs. ?P and ?P vs. ?T) are examined at various temperatures up to 1200 K at zero pressure (P = 0) for the cubic gauche nitrogen. The specific heat (CP) is related to the thermal expansion (?P) and ... -
Pressure dependence of the heat capacity near the melting point in benzene
(Elsevier Science, 2017)The heat capacity C-p is calculated as a function of pressure at constant temperatures of 25, 40 and 51 degrees C for the solid and liquid phases of benzene near the melting point. For this calculation, the observed molar ... -
Pressure effect on the cholesteric – smectic A transition in cholestryl myristate
(Taylor & Francis, 2016)Cholesteryl myristate exhibits tricritical behavior under high pressures close to its cholesteric-smectic A (Ch/SA) transition, as observed experimentally. We study here the thermodynamic properties of this liquid crystal ... -
Principal congruence subgroups in the infinite rank case
(John Wiley and Sons Ltd., 2019)We obtain a number of analogues of the classical results of the 1960s on the general linear groups GLn(Z) and special linear groups SLn(Z) for the automorphism group ?A = Aut(A) of an infinitely generated free abelian group ... -
Raman frequencies calculated at various pressures in phase I of benzene
(KCS Publications, 2013)We calculate in this study the pressure dependence of the frequencies for the Raman modes of A (Ag), B (Ag, B2g) and C (B1g, B3g) at constant temperatures of 274 and 294K (room temperature) for the solid phase I of benzene. ... -
Recombination rate coefficients of boron-like Ne
(The American Astronomical Society, 2013)Recombination of Ne5+ was measured in a merged-beam type experiment at the heavy-ion storage ring CRYRING. In the collision energy range 0–110 eV resonances due to 2s22p › 2s2p2 (?n = 0) and 2s22p › 2s23l (?n = 1), core ... -
The Small Index Property For Free Nilpotent Groups
(TAYLOR & FRANCIS INC, 2015)Let F be a relatively free algebra of infinite rank x.We say that F has the small index property if any subgroup of Gamma = Aut(F) of index at most x contains the pointwise stabilizer Gamma(U) of a subset U of F of cardinality ... -
