“…Afterwards, several types of a quarter-symmetric metric connection were studied ( [8,15,21,25,28]). In [11,20,22,26,31,32], the geometric and physic properties of conformal and projective the semi-symmetric metric recurrent connections were studied. And in [23,24] a projective conformal quarter-symmetric metric connection and a generalized quarter-symmetric metric recurrent connection were studied.…”
