چکیده

We provide a new electromagnetic mass model admitting non static conformal symmetry. We conclude that the pressure and density failed to be regular at the origin but gravitational mass is always positive and vanishes in the limit r → 0 i.e. it does not have to tolerate the problem of singularity. Further, we match interior metric with the exterior (Reissner-Nordström) metric and determine the values of the k and r0 parameters expressed in function of mass, charge and radius of the spherically symmetric charged objects i.e. electron. We also find the Kretschmann scalar K = RμναβR μναβ and check for singularity. In addition, the NEC and WEC energy conditions are discussed.

نظریه میدان اسکالر کلاسیک با تقارن همدیس و پتانسیل نامثبت

We review the conformal symmetry group and investigate the isomorphism between the conformal group and O( D,2 ) . We study the classically  conformal invariant  scalar theory in D -dimensions with a non-positive potential . We solve the  equations  of motion  by  assigning O(D-1, 2)symmetry to the classical solutions with broken translational symmetry in all directions. Then we consider a six d...

New symmetries and conservation laws for electromagnetic fields

It is well known that classical conservation laws of energy, momentum, angular momentum and center-of-energy movement of the electromagnetic field are the consequences of the Maxwell equations invariance with respect to Poincare transformations. However, the relativistic invariance does not exhaust all symmetry properties of these equations. A natural question arises whether there exist any oth...

Optimization of Conformal Mapping Functions used in Developing Closed-Form Solutions for Underground Structures with Conventional cross Sections

Elastic solutions applicable to single underground openings usually suffer from geometry related simplification. Most tunnel shapes possess two axes of symmetry while a wide range of geometries used in tunneling practice involve only one symmetry axis. D-shape or horse-shoe shape tunnels and others with arched roof and floor are examples of the later category (one symmetry axis). In the present...

Static Cylindrical Symmetry and Conformal Flatness

We present the whole set of equations with regularity and matching conditions required for the description of physically meaningful static cylindrically symmmetric distributions of matter, smoothly matched to Levi-Civita vacuum spacetime. It is shown that the conformally flat solution with equal principal stresses represents an incompressible fluid. It is also proved that any conformally flat c...

Electromagnetic propagators in hyperbolic Robertson–Walker cosmologies

Green functions ~retarded, advanced, Feynman and Dyson propagators! are calculated for the electromagnetic field in Robertson–Walker cosmologies with hyperbolic 3-manifolds as spacelike slices. The starting point is the Proca equation, i.e., the Maxwell field with a finite photon mass for infrared regularization, in a static cosmology with simply connected hyperbolic 3-sections. The time and sp...
