A point x ∈ C is a fixed point of T provided Tx = x. Denote by F(T) the set of fixed points of T ; that is, F(T)= {x ∈ C : Tx = x}. It is assumed throughout the paper that T is a nonexpansive mapping such that F(T) =∅. One classical way to study nonexpansive mappings is to use contractions to approximate a nonexpansive mapping [1, 9]. More precisely, take t ∈ (0,1) and define a contraction Tt :...

Understanding the process and underlying mechanisms of speciation remains a challenging subject in evolutionary biology. Identifying genes that are essential to confer reproductive isolation is difficult and time consuming, and those that have been described as ‘speciation genes’ vary in terms of demonstrable effect (Swanson & Vacquier, 2002; Tregenza, 2002; Noor, 2003; Pitnick et al., 2003; Ri...

Bu çalışmanın temel amacı Oğuz grubu yazı dillerinin birbirlerine karşı fonetik uzaklıklarını tespit etmektir. Çalışmada uzaklıkların tespiti için bilgisayarlı dil bilim alanında sıkça kullanılan niceliksel ölçüm tekniklerinden Levenshtein uzaklık algoritması kullanılmıştır. bağlamda, Türkiye’deki lehçe araştırmalarında kullanılabilecek bir yöntemi tanıtarak ilgili alanda yeni değerlendirmeleri...
