Computation, 2016 An extremely interesting problem in aero-hydrodynamics is the sound radiation of a single vortical structure. Currently, this type of problem is mainly considered for an incompressible medium. In this paper a method was developed to take into account the

Coulomb Problem for Classical Spinning Particles
Universe, 2023 We consider the motion of a weakly relativistic charged particle with an arbitrary spin in central potential e/r in terms of classical mechanics. We show that the spin–orbital interaction causes the precession of the plane of orbit around the vector of ...

On Quantum Field Theory. I: Quantum Field Theory as Quantum Mechanics [PDF]
Progress of Theoretical Physics, 1974 Summary: A new approach to finding a steady foundation of quantum field theory is investigated with the help of the so-called nonstandard mathematics. We construct a model of the quantum field theory as a quantum-mechanical system with very many degrees of freedom.

Quantum Gravity as Topological Quantum Field Theory [PDF]
, 1995 The physics of quantum gravity is discussed within the framework of topological quantum field theory. Some of the principles are illustrated with examples taken from theories in which space-time is three dimensional.Comment: 23 pages, amstex, JMP special

Quaternionic Quantum Field Theory [PDF]
Physical Review Letters, 1985 Abstract Up to this point our discussion of relativistic quaternionic wave equations has dealt with the first quantized case, in which the wave fields are quaternions in the right-acting algebra spanned by 1, i,j,k, with c-number-valued real components.

Field Redefinition Invariance in Quantum Field Theory [PDF]
, 2000 The issue of field redefinition invariance of path integrals in quantum field theory is reexamined. A ``paradox'' is presented involving the reduction to an effective quantum-mechanical theory of a $(d+1)$-dimensional free scalar field in a Minkowskian ...
