This thesis consists of three sections. The first section is reserved for introduction,
some basic definitions and declaration of literature about alpha-psi type contractive mappings and related fixed point theorems have been presented. The second
section deals with the main results. We have applied definition of alpha-admissible
for two different functions of f and T. Furthermore, we have investigated their
results. Finally, the third section includes discussion and conclusion.
Bu ¸calı¸sma ¨u¸c b¨ol¨umden olu¸smu¸stur. Birinci b¨ol¨um giri¸s,temel tanımlar,literat¨ur
bilgileri alpha-psi tipinden b¨uz¨ulme d¨on¨u¸s¨umleri ve ilgili sabit nokta teoremlerine
ayrılmı¸stır. ˙Ikinci b¨ol¨umde ana fikri verdik. Alpha-admissible tanımını iki farklı
fonksiyon olan f ve T i¸cin uyguladık ve sonu¸clarını inceledik. U¸c¨unc¨u b¨ol¨umde ¨
sonu¸c ve tartı¸smalara yer verdik.
