The solutions of generalized Klein-Gordon equations are considered. The generalizations of the Klein-Gordon equation allow one to derive convergent integrals for the Green functions of these equations. The generalized equations are presented as produ... see more

New classification of particles is proposed. This classification is based on U(Nf,g) ×SU(3c)×SU(4, fs)×O(3) -group, where U(Nf,g) corresponds to the particle generations, SU(3,c) - to the color, SU(4,fs) - to the flavor and the spin (instead of known SU(6... see more

It is a remarkable occurence that if two Lagrangians differ up to the total time derivative of an arbitrary function of coordinates and time they are dynamically equivalent, i.e., they imply the same equations of motion despite these Euler-Lagrange equati... see more

Kuat medan tensor yang ditransformasikan secara homogen terhadap perluasan transformasi gauge memenuhi bentuk sifat invarian gauge. Analisa invarian gauge dalam bantuk integeralnya memperlihatkan hubungan dengan koordinat ruang-waktu yang menunjukan bentu... see more

In this paper we formulate singular theories (determined by degenerate Lagrangians) without involving constraints. We construct a partial Hamiltonian formalism in reduced phase space (with arbitrary number of momenta). The equations of motion are fir... see more

In this contribution a careful critical reading of the feasibility to express a Lagrangian function as the sum of several terms each having a different degree of homogeneity with respect to the velocities is presented. Arguments are proposed so to overcom... see more

Functional realizations of Lie algebras are applied to the problem of determining Lie and Noether point symmetries of Lagrangian systems in N dimensions, particularly in the plane. This encompasses both the case of symmetry-preserving perturbations of a g... see more

Path integral formulation of quantum mechanics (and also other equivalent formulations) depends on a Lagrangian and/or Hamiltonian function that is chosen to describe the underlying classical system. The arbitrariness presented in this choice leads to a p... see more
