This has several applications in physical cosmology,[9] including the formation of the light elements in Big Bang nucleosynthesis, the production of dark matter and baryogenesis. [14] More generically the study of processes in the early universe often attempt to take into account the effects of quantum mechanics and general relativity. {\displaystyle p_{i}} Letting i For other uses, see, The collision term (Stosszahlansatz) and molecular chaos, Quantum theory and violation of particle number conservation. In algebra lineare, il momento di un vettore è uno pseudovettore definito come prodotto vettoriale della posizione del vettore, relativa a un punto detto polo, per il vettore stesso.Il termine viene talvolta adoperato con un'accezione scalare: è il caso ad esempio delle grandezze come il momento statico e il momento di inerzia.. A causa della natura vettoriale di molte grandezze … k The non-relativistic form of L is, It is possible to write down relativistic quantum Boltzmann equations for relativistic quantum systems in which the number of particles is not conserved in collisions. Define Moment of Inertia [11] is, where Γαβγ is the Christoffel symbol of the second kind (this assumes there are no external forces, so that particles move along geodesics in the absence of collisions), with the important subtlety that the density is a function in mixed contravariant-covariant (xi, pi) phase space as opposed to fully contravariant (xi, pi) phase space.[12][13]. V {\displaystyle w_{i}} A {\displaystyle A={\frac {p_{i}p_{i}}{2m}}} Le moment cinétique est le moment d'une impulsion angulaire (alors que l’action est le moment d'une impulsion simple) I l se rapporte donc à une rotation.Mais comme on distingue plusieurs types de rotations (dans le plan ou dans l'espace, ou dans les 2), il faut également distinguer plusieurs types de moments cinétiques. is the local Maxwellian distribution function given the gas temperature at this point in space. A galaxy, under certain assumptions, may be approximated as a continuous fluid; its mass distribution is then represented by f; in galaxies, physical collisions between the stars are very rare, and the effect of gravitational collisions can be neglected for times far longer than the age of the universe. ) Phys., 52, 299; The classic example of such a system is a fluid with temperature gradients in space causing heat to flow from hotter regions to colder ones, by the random but biased transport of … The collisionless Boltzmann equation, where individual collisions are replaced with long-range aggregated interactions, e.g. La sua attività è Codice Ateco 2007 (45.11.01) "Commercio all'ingrosso e al dettaglio di autovetture e di autoveicoli leggeri".
