Abstract. We present the coordinate transformations which
transform
the diagonal Minkowski metric tensor in a metric tensor with all zero
diagonal
components. Some of the obtained coordinate transformations provide the
singular metric tensors and we point out those ones which provide the
nonsingular
metrics.
Key words: the diagonal Minkowski metric tensor, zero diagonal
components, coordinate transformation.
METRIČKI TENZOR SA NULTIM ELEMENTIMA
NA DIJAGONALI
Prikazujemo koordinatne transformacije koje metriku Minkovskog prevode
u metriku čiji su svi dijagonalni elementi jednaki nuli. Našli smo
nekoliko
rešenja i istakli smo ona rešenja koja daju nesingularan metrički
tenzor.
Ključne reči: dijagonalni metrički tenzor Minkowskog, nulti
dijagonalni elementi, transformacije koordinata.
