Hermitian eigenvalue problem and its generalization to any semisimple group: A survey

Shrawan Kumar

University of North Carolina at Chapel Hill

**Abstract:** The classical Hermitian eigenvalue problem asks the following question: What are the possible eigenvalues of the sum A + B of two n × n Hermitian matrices A and B, provided we fix the eigenvalues of A and B. A systematic study of this problem was initiated by H. Weyl (1912). By the contributions from a long list of mathematicians, notably Weyl (1912), Horn (1962), Klyachko (1998) and Knutson-Tao (1999), the problem was finally settled. The solution asserts that the eigenvalues of A + B are given in terms of certain system of linear inequalities in the eigenvalues of A and B. These inequalities are given explicitly in terms of certain triples of Schubert classes in the singular cohomology of Grassmannians and the standard cup product. The Hermitian eigenvalue problem has been extended by Berenstein-Sjamaar (2000) and Kapovich-Leeb-Millson (2005) for any semisimple complex algebraic group G. Their solution is again in terms of linear inequalities obtained from certain triples of Schubert classes in the singular cohomology of the partial flag varieties G/P (P being a maximal parabolic subgroup) and the standard cup product. However, their solution is far from being optimal. In a joint work with P. Belkale, we have given an optimal solution of the problem for any G. We define a deformation of the cup product in the cohomology of G/P and use this new product to generate certain inequalities which optimally solves the problem for any G. The talk should be accessible to general mathematical audience.

IMBM matematiğin çeşitli alanlarında araştırma yapılması amacıyla kurulmuş bir merkezdir. Merkez gerekli yer, zaman ve hizmetleri sunarak araştırmacıların birlikte çalışacağı bir ortam yaratmayı hedefler. Mevcut araştırma merkezleri ve enstitüler ile ortaklaşa çalışmalar yapar.

Bağımsız bir kurum olmakla birlikte, kampüsünde yer aldığı Boğaziçi Üniversitesi ile sıkı bir işbirliği içindedir.

Merkezin ders programları yoktur, diploma vermez. Bununla birlikte lisansüstü seminerler ve doktora sonrası çalışmaları aracıyla genç matematikçilerin yetişmesine katkıda bulunmayı hedefler. Bir başka amacı da kamuda matematiksel bilincin gelişmesine katkıda bulunmaktır.

IMBM mali kaynağını bağış geliri, kamu ve özel kuruluşlar ile işbirliği anlaşmaları, şirket ve bireylerin bağışları yoluyla elde eder. Matematikçilerin bütçesi merkezden, kendi çalıştıkları kurumlardan veya işbirliği içinde olunan araştırma merkezleri, enstitüler ve üniversiteler gibi çeşitli kaynaklardan sağlanır.

IMBM iki komite tarafından yönetilir.

Merkezimizin kurucularından ve ilk eş yöneticilerinden Betül Tanbay tarafından sunulan (2006-2012 yılları arasında hizmet verilen) ve EMS Bülten Eylül 2010'da yayınlanan merkezimizin kuruluş yıllarının kısa bir tarihçesine şu adresten ulaşabilirsiniz.

IMBM destek veren kuruluşların da temsil edildiği İşletme Komitesi tarafından idare edilir. İşletme Komitesi yönetim ve mali konular ile ilgilenir. Uluslararası araştırma gücü kabul edilmiş üyelerden oluşan Bilimsel Yönlendirme Komitesi bilimsel stratejileri ve programları belirler. Uluslararası Bilimsel Danışma Komitesi bilimsel program ve diğer faaliyetleri değerlendirir.

İstanbul çok büyük bir şehir ancak geniş bir toplu taşıma ağına sahiptir. Ulaşım ücretleri oldukça makuldür. Bir yerden diğerine gitmek uzun sürebilir, gözünüzü korkutmayın, sabırlı olun. Seçtiğiniz rotaya bağlı olarak metro, metrobüs, otobüs, dolmuş, HAVABUS, taksi ya da bunların birlikte kullanımı mümkündür. Bazı ipuçları şu şekilde:

Araçlarda bilet satın alamazsınız. Toplu taşımayı birçok kez kullanmayı planlıyorsanız, şehrin her yerindeki metro istasyonlarında veya büfelerde bulunan bir otomattan ön ödemeli bir ISTANBULKART satın alın. İstanbulKart satın alırken, iade edilmeyen 6 TL'lik bir ücret (asıl kart ve hizmet için) artı karta yüklemek için seçtiğiniz bir miktar ödemelisiniz. İstanbulKart kullanırsanız otomatik olarak transfer indirimi alırsınız. Hava alanlarından gelmek / hava alanlarına gitmek dışında toplu taşıma kullanmayacaksanız, içinde birkaç yolculuk olan kartlar satın alabilirsiniz. Bu kartlarla transfer indiriminiz yoktur.

Taksiler genelde güvenilirdir ancak yine de şoförün sayacı açtığından emin olun.

Aşağıda verilen yolculuk süreleri ve fiyatlandırmaları ortalamadır. Trafiğin durumuna göre değişebilmektedir.

İstanbul Havalimanı (IST) ve Boğaziçi Üniversitesi Kuzey ve Güney Kampüsleri İstanbul'un Avrupa yakasındadır.

Sabiha Gökçen Uluslararası Havalimanı (SAW) İstanbul'un Asya yakasında yer almaktadır.

IMBM ve Kennedy Lodge Güney Kampüstedir.

IMBM, Boğaziçi Üniversitesi Güney Kampüsü'nde yer almaktadır. Güney Kampüsün ana girişinden Merkeze ulaşmak için aşağıdaki Harita.1'deki kırmızı yolu takip edin.

Harita.1

Güney Kampüste, yukarıdaki Harita.1'de turuncu daire ile işaretlenmiştir. Kampüsün güvenlik görevlilerine yolunuzu sorabilirsiniz.

Güney Kampüste, yukarıdaki Harita.1'de mavi daire ile işaretlenmiştir. Kampüsün güvenlik görevlilerine yolunuzu sorabilirsiniz.

Güney Kampüste, yukarıdaki Harita.1'de beyaz daire ile işaretlenmiştir. Kampüsün güvenlik görevlilerine yolunuzu sorabilirsiniz.

Bu bina Kuzey kampüsünde yer almaktadır. Güney Kampüs'ün ana kapısına ulaştığınızda, aşağıdaki Harita 2'de gösterilen turuncu rotayı takip edin. Kuzey Kampüs'ün güvenlik görevlilerine yolunuzu sorabilirsiniz. 3 numaralı Yurda gideceğinizi söyleyin.
