Feynman Integrals Associated with Albeverio{hhegh-krohn Potentials
Let be a nite measure on R such that (R n f0g) > 0 and R R e cjj dd() < 1 for any c > 0. Deene a growth function w by w(r) = expp R R (e p r jj ? 1) dd()]; r 0 and let u be the Legendre transform of w. Let S] u be the space of generalized functions arising from a white noise space and the function u. It is shown that the Feynman integrand with Albeverio{HHegh-Krohn potential b is a generalized ...
متن کاملEccentric stellar discs with strong density cusps and separable potentials
We introduce a class of eccentric discs with “strong” density cusps whose potentials are of Stäckel form in elliptic coordinates. Our models exhibit some striking features: sufficiently close to the location of the cusp, the potential and surface density distribution diverge as Φ ∝ r and Σ ∝ r, respectively. As we move outward from the centre, the model takes a non-axisymmetric, lopsided struct...
متن کاملStellar Dynamics of Dense Stellar Systems
Stellar dynamics is almost unreasonably well suited for an implementation in terms of special-purpose hardware. Unlike the case of molecular dynamics, stellar dynamics deals exclusively with a long-range force, gravity, which leads to a computational cost scaling as the square of the number of stars involved. While special tricks can lead to a reduction of this cost from ∼ N2 to ∼ N logN in the...
متن کاملThe Stellar Dynamics Toolbox
NEMO is a toolbox for users and programmers with which a wide range of experimental situations can be constructed, dynamically evolved, and analyzed. Primarily geared towards stellar dynamics, NEMO is by no means restricted to it. Great importance has been given to making the package extendible and to exibly import and export data. NEMO has been implemented within, and integrated into, the UNIX...
متن کاملThe Stellar Dynamics of !
The stellar dynamics of ! Centauri are inferred from the radial velocities of 469 stars measured with CORAVEL (Mayor et al. 1997). Rather than t the data to a family of models, we generate estimates of all dynamical functions nonparametrically, by direct operation on the data. The cluster is assumed to be oblate and edge-on but mass is not assumed to follow light. The mean motions are consisten...
