• Abstract: Complex particle is a kind of bilocal particle having unexpected symmetry, which was proposed by the authour. In the present paper, we show that critical dimension of the complex particle in Minkowski spacetime is $D = 4$, while $D = 2, 4$ or $6$ are permitted in Euclid spacetime. The origin of the restriction to the dimension is the existence of tertiary constraint in the canonical theory, quantization of which leads to an eigenvalue equation having single-valued and bounded solutions only in particular dimension of spacetime. The derivation is based on a detailed analysis of Laplace-Beltrami operator on $S^{1,D-2}$ or $S^{D-1}$.

  We show that the covariant phase space of the supersymmetric version of the relativistic oscillator is the odd tangent bundle of the space $Z_6$. We obtain components of the spinor field that are holomorphic and antiholomorphic functions from Bergman spaces on $Z_6$ with different weight functions.

  We show that the conjecture is true for the real part of the ground state energy and of the excited state energies. The analogous relation for partition functions in zero spacetime dimensions is valid for many cases. The possibility that the conjecture is valid, for a single component field theory in higher dimensional spacetimes, is discussed.

  We show how to reduce the geometry of degenerate states to the non-abelian connection $A$. We find independent invariants associated with each triple of subspaces. Some of them generalize the Berry-Pancharatnam phase, and some do not have analogues for 1-dimensional subspaces.

We will lift the bundles $L_Cpm$ and connection $A_hbar$ on them to the relativistic phase space $T*R3,1$ and couple them to the Dirac spinor bundle describing both particles and antiparticles.

  We elaborate the definition and properties of "massive" elementary systems in the $(1+3)$-dimensional Anti-de Sitter (AdS$_4$) spacetime. We reveal the dual nature of "massive" elementary systems living in AdS$_4$ spacetime, as each being a combination of a Minkowskian-like elementary system. This duality will take its whole importance in the quantum regime in view of its possible role in the explanation of the current existence of dark matter.

  Quantum systems governed by non-Hermitian Hamiltonians with $PT$ symmetry are special in having real energy eigenvalues bounded below and unitary time evolution. We show how $PT$ symmetry may allow interpretations that evade ghosts and instabilities present in an interpretation of the theory within a Hermitian framework.

  We consider an integral equation describing a fixed number of scalar particles which interact directly along light cones. We treat the highly singular case that interactions occur exactly at zero Minkowski distance. We also extend the existence and uniqueness result to an arbitrary number $N geq 2$ of particles.
