Structure of the Fixed Point of Condensing Set-Valued Maps
In this paper, we present structure of the fixed point set results for condensing set-valued map. Also, we prove a generalization of the Krasnosel'skii-Perov connectedness principle to the case of condensing set-valued maps.
متن کاملFurther Comments on a Vanishing Singlet Axial Vector Charge
The recent suggestion of a vanishing flavor-singlet axial charge of nucleon due to a nontrivial vacuum structure is further amplified. A perturbative QCD discussion, applicable for the heavy quark contributions, relates it to the physics of the decoupling theorem. It is also shown that g A ≃ 0 leads to a negative η-meson-quark coupling, which has been found to be compatible with the chiral quar...
متن کاملAxial structure of the nucleon
We review the current status of experimental and theoretical understanding of the axial nucleon structure at low and moderate energies. Topics considered include (quasi)elastic (anti)neutrino–nucleon scattering, charged pion electroproduction off nucleons and ordinary as well as radiative muon capture on the proton. PACS numbers: 11.40.-q, 25.30.Rw, 23.40.-s, 25.30.Pt, 12.39.Fe Submitted to: J....
متن کاملNucleon axial charge and structure functions with domain wall fermions
Domain wall fermions (DWF) [1] have been successfully used by the RBC Collaboration for several applications [2]. In the baryon sector we had reported that DWF with Wilson gauge action in the quenched approximation can reproduce the first negative-parity excited state of nucleon [3] which defied theoretical attempts for a long time. Here we report the current status of our calculations on the n...
متن کاملTri-axial Octupole Deformations and Shell Structure
The remarkable regularity of rotational spectra of superdeformed nuclei has prompted many investigations into the contribution of higher multipoles on the formation of shell structure [1]. Related questions have arisen for other mesoscopic systems. In particular, it appears that octupole deformation has the same importance for two-dimensional systems like quantum dots and surface clusters [2] a...
