Some paradoxes in mathematics
(Doğuş Üniversitesi, 2000-01-15)We have explained some paradoxes in the set theory of mathematics. -
Professor Masatoshi Gündüz Ikeda: a life devoted to mathematics
(TÜBİTAK, 2003)In the summer of 1963 as a new graduate I paid a visit to the newly established Mathematics Department of Ege University, in _Izmir, to apply for a post. In the very moments of my arrival, they introduced to me a young ... -
Non-hamming (rosenbloom-tsfasman) metriğine göre kodların yapısı
(Anadolu Üniversitesi, 2004)Bu çalışmada ρ metriğine göre lineer kodların yapıları incelendi. Kodların yapılarından faydalanılarak, bu met-riğe göre lineer ve devirli kodların minimum uzaklığının kolaylıkla tespit edilebildiği gösterildi. Bu metriğe ... -
On automorphic and modular forms in the space of the homogeneous polynomials with degree 2l and applications to the special matrix
(Elsevier, 2004-05-13)An interesting connection exists between the space of homogeneous polynomials and the representations of the homogeneous modular group F(l). This linkage leads to become automorphic and modular forms for the representations ... -
On the prime radical of a module over a noncommutative ring
(The Mathematical Society of the Republic of China, 2004-06)Let R be a ring and M a left R - module. The radical of M is the intersection of all prime submodules of M. It is proved that if R is a hereditary, noetherian, prime and non right artinian and M a finitely generated R-module ... -
