Generalized catalan numbers, sequences and polynomials
(TÜBİTAK, 2010)In this paper we present an algebraic interpretation for generalized Catalan numbers. We describe them as dimensions of certain subspaces of multilinear polynomials. This description is of utmost importance in the investigation ... 
A generalized fixed point free automorphism of prime power order
(World Scientific Publishing, 201206)Let G be a finite group and α be an automorphism of G of order pn for an odd prime p. Suppose that α acts fixed point freely on every αinvariant p′section of G, and acts trivially or exceptionally on every elementary ... 
A generalized fixedpointfree action
(World Scientific Publishing, 201305)In this paper we study the structure of a finite group G admitting a solvable group A of automorphisms of coprime order so that for any x ∈ CG(A) of prime order or of order 4, every conjugate of x in G is also contained ... 
Global attractors for the 3D viscous cahnhillard equations in an unbounded domain
(Taylor & Francis, 200908)In this note the 3D viscous CahnHillard equation is considered in an unbounded domain. It is shown that the semigroup generated by this equation has a global attractor. The asymptotic compactness of the solution operator ... 
Global existence and open loop exponential stabilization of weak solutions for nonlinear schrodinger equations with localized external neumann manipulation
(Elsevier, 201303)In this paper, we consider the nonlinear Schrodinger equations (NLS) with (focusing/defocusing) interior source and (possibly nonlinear) damping on a bounded regular domain in the Euclidean space. Moreover, it is assumed ... 
Groups of automorphisms with TNIcentralizers
(Elsevier, 201803)A subgroup H of a finite group G is called a TNIsubgroup if NG(H)∩Hg=1 for any g∈G\NG(H). Let A be a group acting on G by automorphisms where CG(A) is a TNIsubgroup of G. We prove that G is solvable if and only if CG(A) ... 
Infinite  dimensional symmetries of two  dimensional generalized Burgers equations
(American Institute of Physics, 201007)The conditions for a class of generalized Burgers equations which a priori involve nine arbitrary functions of one or two variables to allow an infinitedimensional symmetry algebra are determined. Although this algebra ... 
The influence of Hughes type action
(Taylor & Francis, 2015)We call the action of an automorphism of a finite group G a Hughes type action if it is described by conditions on the orders of elements of GG. In the present paper we study the structure of finite group G admitting an ... 
Isospectral mathieu  hill operators
(Springer Verlag, 201308)In this paper we prove that the spectra of the MathieuHill Operators with potentials ae(i2 pi x) +be (i2 pi x) and ce(i2 pi x) +de (i2 pi x) , where a, b, c and d are complex numbers, are the same if and only if ab = ... 
Multiplication lattice modules
(Shiraz University, 2011)Let M be a lattice module over the multiplicative lattice L. An Lmodule M is called a multiplication lattice module if for every element N is an element of M there exists an element a is an element of L such that N = ... 
Nilpotent length of a finite solvable group with a frobenius group of automorphisms
(Taylor & Francis, 20140523)We prove that a finite solvable group G admitting a Frobenius group FH of automorphisms of coprime order with kernel F and complement H such that [G, F] = G and C C G (F)(h) = 1 for all nonidentity elements h ∈ H, is of ... 
Nonhamming (rosenbloomtsfasman) metriğine göre kodların yapısı
(Anadolu Üniversitesi, 2004)Bu çalışmada ρ metriğine göre lineer kodların yapıları incelendi. Kodların yapılarından faydalanılarak, bu metriğe göre lineer ve devirli kodların minimum uzaklığının kolaylıkla tespit edilebildiği gösterildi. Bu metriğe ... 
Nonselfadjoint sturm–liouville operators with matrix potentials
(Pleiades Publishing, 2007)We obtain asymptotic formulas for nonselfadjoint operators generated by the Sturm–Liouville system and quasiperiodic boundary conditions. Using these asymptotic formulas, we obtain conditions on the potential for which ... 
On a semi symmetric metric connection with a special condition on a Riemannian manifold
(European Journal of Pure and Applied Mathematics, 2011)In this study, we consider a manifold equipped with semi symmetric metric connection whose the torsion tensor satisfies a special condition. We investigate some properties of the Ricci tensor and the curvature tensor of ... 
On automorphic and modular forms in the space of the homogeneous polynomials with degree 2l and applications to the special matrix
(Elsevier, 20040513)An interesting connection exists between the space of homogeneous polynomials and the representations of the homogeneous modular group F(l). This linkage leads to become automorphic and modular forms for the representations ...
