Webgij:= ei ¢ej: (1.3) It is a second rank tensor and it is evidently symmetric. If it is furthermore (everywhere) diagonal, the coordinates are called locally orthogonal. The dual tensor is denoted as gij, so that we have gijg jk = –k i = ‰ 1 if i= k 0 if i6= k; (1.4) where –k i is called the Kronecker symbol. Web1 Introduction.

Webij = 8 >< >: 1 if i= j, 0 otherwise. (1.6) The Kronecker delta assumes nine possible values, depending on the choices for iand j. For example, if i = 1 and j = 2 we have 12 = 0, because iand jare not equal. If i= 2 and j= 2, then we get 22 = 1, and so on. A convenient way of remembering the de nition (1.6) is to imagine WebSep 7, 2024 · Itulah yang dinamakan sebagai pola divergent, muncul nya pola tersebut membuat market akhirnya kembali membuat trend turun.
