Program tanımları MATEMATİK ANABİLİM DALI LİSANSÜSTÜ PROGRAMLARI
Matematik kabul edilebilir aksiyomlar üzerine kurulu, mantık kurallarıyla çıkarımlar yapılan, mutlak denilebilecek gerçekliğe sahip bir çalışma alanıdır. Aksiyom ve sonuçların fiziksel gerçeklikle örtüştüğü durumlarda hemen hemen bütün bilim ve mühendislik dallarının konu edilebileceği uygulamalı matematik söz konusudur. Bilginin ve bilimin hızla değer kazanarak teknoloji, sanayi ve finans dünyasını şekillendirdiği günümüzde; matematik ve matematiksel düşünce hem değişik akademik alanlarda araştırma yapmak isteyenler hem de profesyonel iş yaşamını hedefleyenler için bir gerekliliktir.
Matematikte lisans ve/veya yüksek lisans derecesi ile iş bulabilmek çoğu zaman uygulamalı matematiğin bazı alanlarında ve bilgisayar bilimlerinde eğitimi gerektirmektedir.
Geleneksel uygulamalı matematik, fiziksel bilimlere (fizik, mühendislik, endüstri vb) yönelimli matematik anlamındadır ve bu alanlarda son derece geniş bir yelpazede çalışma olanağı vardır. Finas kuramcıları, ekonomistler, mühendisler, fizikçiler, bir kısım biyolog, kimyacı vb meslek sahiplerinin, kendilerine matematikçi denmese bile, iyi ve yeterli matematik eğitimi almış olmaları gerekmektedir.
Öte yandan, karar verme bilimleri denilebilecek operasyon analizi, sistem analizi vb için, matematik ve sistem mühendisliğinin birinde lisans diğerinde yüksek lisans derecesi almak oldukça uygun bir eğitim olabilir. Aktuarya (sigortacılık) ve işletme için lineer cebir ve istatistik, bilgisayar bilimlerinde özellikle yazılım ve ağ mühendisliği konularında mantık, kombinatorik, sayılar kuramı ve cebir gerekli matematik olarak görülmektedir.
Ortaöğrenim ve lise matematik öğretmenlerinin geniş bir matematik kültürüne sahip olmaları öğrettikleri parçaların bütün içindeki yerini gösterebilmeleri ve öğrenciler üzerinde matematik hakkında iyi bir izlenim bırakabilmeleri bakımından gereklidir.
Bu veriler ışığında hazırlanan Matematik Yüksek Lisans ve Doktora programları Fen ve Mühendislik Fakülteleri (Matematik, Fizik, Kimya, Biyoloji bölümleri ile Makine, Elektrik ve Elektronik, Bilgisayar, Sistem, Kimya Mühendislikleri bölümleri) ile Eğitim Fakültelerinin temel bilimler bölümlerinden Lisans ve Yüksek Lisans dereceleri alan öğrencilerin tümüne açık bir programdır.
Yetenekli ve matematiği seven öğrencilerin doktora derecesi alarak üniversitede eğitim ve araştırma çalışmalarını hedeflemeleri idealdir. Bu alandaki iş fırsatları ülkemizde (özellikle batılı ülkelere göre) daha fazladır. Doktora mezunları araştırma grupları bulunan büyük şirketlerde ve devlet kurumlarında da iş bulabilirler.
Başka bir Enstitüde bir yarıyılını başarı ile tamamlayan öğrenciler de programlara başvurabilirler.
Doktora programına, Yüksek Lisans derecesi ile kabul edilen öğrenciler yirmibir kredilik yedi ders almalı ve tez çalışması yapmalıdır. Lisans derecesi ile kabul edilen öğrenci en az kırkiki kredilik ondört ders almalı ve tez çalışması yapmalıdır. Derslerden altı tanesi zorunludur. Yedi dersini tamamlayan öğrenci dilerse Yüksek Lisans programına geçebilir.
Matematik Bölümü araştırma görevlilerini lisanüstü öğrencileri arasından seçmeyi benimsemektedir.
Doğrusal olmayan türevli denklemler, dinamik sistemler, türevsel geometri, fonksiyonel analiz, yaklaşım kuramı, tam çözülebilir sistemler, Hamilton yapıları, simplektik geometri, geometrik mekanik, Lie grupları ve Lie cebirleri bölümün temel araştırma alanlarına örnek olarak sayılabilir. Lisanüstü derslerin yanısıra düzenli seminerler öğrencileri çalışma alanlarında daha ileri düzeye taşımayı hedeflemektedir. Seminerlerin konusu bölüm elemanlarının ve ziyaretçilerin araştırma konularına göre zamanla değişmektedir.
