Schwarz-Christoffel: piliero en rivero (a pillar on a river)
F. M. Paiva, A. F. F. Teixeira
La transformoj de Schwarz-Christoffel mapas, konforme, la superan kompleksan duon-ebenon al regiono limigita per rektaj segmentoj. Cxi tie ni priskribas kiel konvene kunigi mapon d…
Algorithm for structure constants
F. M. Paiva, A. F. F. Teixeira
In a -dimensional Lie algebra, random numerical values are assigned by computer to especially selected structure constants. An algorithm is then created, which calculat…
Tempa voja^go kaj geodezioj en ^generala relativeco / Time travel and geodesics in general relativity
F. M. Paiva, A. F. F. Teixeira
In the homogeneous metric of Som-Raychaudhuri, in general relativity, we study the three types of geodesics: timelike, null, and spacelike; in particular, the little known geodesic…
Doppleraj efikoj ĉe Schwarzschild
F. M. Paiva, A. F. F. Teixeira
Motion of bodies and light rays are studied in the gravitational field of Schwarzschild. Several Doppler effects are described. ----- Movado de korpoj kaj lumo estas studitaj en gr…
Relativeca Dopplera efiko inter du akcelataj korpoj - I
F. M. Paiva, A. F. F. Teixeira
We describe the Doppler effect between equally accelerated light source and observer under the special relativity. The proper accelerations are constant and parallel. An English ve…
La relativeca tempo - I / The relativistic time - I
F. M. Paiva, A. F. F. Teixeira
The relativistic time is different from the Newtonian one. We revisit some of these differences in Doppler effect, twin paradox, rotation, rigid rod, and constant proper accelerati…
