Nonsingular complex instantons on Euclidean spacetime

... Our starting point is a complex version of the harmonic function ansatz due to ’t Hooft and outlined in [11]. We show that to each holomorphic function f : C2 → C one can associate a smooth, anti-self-dual SL(2, C)-connection on R4 of zero action density which is not pure gauge. Motivated by the ext ...

Introduction the theory of persistence of quasiperiodic solutions

... Quasiperiodic functions are, roughly, functions which can be expressed with a finite number of frequencies. They appear naturally in nature when there are several independent processes each of them with a natural frequency. They were considered since antiquity as models of the motion of the planets. ...

Radiation and quantised orbits

... What goes on in the atom is essentially quantum mechanical. The laws of classical physics simply do not fully explain what is going on there. Think of the electron in orbit, in a classical situation it is accelerating and will therefore radiate energy. However Bohr's theory forbids this unless there ...
