in this paper we prove existence the common fixed point with different conditions for $alpha-psi$-contractive mappings. and generalize weakly zamfirescu map in to modified weakly zamfirescu map.

a primigravida who had been in labour fortyeight hours, with a large baby, a weakly contracting uterus, a good pulse and a flat pelvis, above whose brim the baby's head was floating freely. The membranes had ruptured early in labour and there was no sign of foetal life, but I thought it worth trying a forceps extraction before proceeding to craniotomy. Low Csesarean section was then in its earl...

It is known that all weakly conformal Hamiltonian stationary Lagrangian immersions of tori in CP may be constructed by methods from integrable systems theory. This article describes the precise details of a construction which leads to a form of classification. The immersion is encoded as spectral data in a similar manner to the case of minimal Lagrangian tori in CP, but the details require a ca...

We present approximate solutions for the gluon and ghost propagators as well as the running coupling in Landau gauge Yang–Mills theories. We solve the corresponding Dyson–Schwinger equations in flat Euclidean space-time without any angular approximation. This supplements recently obtained results employing a four-torus, i.e. a compact space-time manifold, as infrared regulator. We confirm previ...

banach contraction principle has been generalized in different spaces by mathematicians over the years. mustafa and sims [18] proposed a new class of generalized metric spaces, which are called as g-metric spaces. in this type of spaces a non-negative real number is assigned to every triplet of elements. many mathematicians studied extensively various results on g-metric spaces by using the con...

By an argument similar to that of Gibbons and Stewart (1984 Absence of asymptotically flat solutions of Einstein’s equations which are periodic and empty near infinity Classical General Relativity (London, 1983) ed W Bonnor, J N Islam and M A H Callum (Cambridge: Cambridge University Press) pp 77– 94), but in a different coordinate system and less restrictive gauge, we show that any weakly asym...

Hybrid free-surface flows past disturbances in a two-dimensional channel are identified and studied. The fluid is assumed to be inviscid and incompressible, and the flow to be steady and irrotational. The disturbances consist of a step in the bottom of the channel and a flat object lying on the free-surface (e.g., a sluice gate). A weakly nonlinear one-dimensional analysis is used to classify t...

A large class of technically non-chaotic systems, involving scatterings of light particles by flat surfaces with sharp boundaries, is nonetheless characterized by complex random looking motion in phase space. For these systems one may define a generalized, Tsallis type dynamical entropy that increases linearly with time. It characterizes a maximal gain of information about the system that incre...

Terahertz absorption spectra have been recorded for the weakly bound CO2-H2O complex embedded in cryogenic neon matrices at 2.8 K. The three high-frequency van der Waals vibrational transitions associated with out-of-plane wagging, in-plane rocking, and torsional motion of the isotopic H2O subunit have been assigned and provide crucial observables for benchmark theoretical descriptions of this ...

We study a symmetry, schematically Energy → – Energy, which suppresses matter contributions to the cosmological constant. The requisite negative energy fluctuations are identified with a “ghost” copy of the Standard Model. Gravity explicitly, but weakly, violates the symmetry, and naturalness requires General Relativity to break down at short distances with testable consequences. If this breakd...
