There is no branch of mathematics, however abstract, which may not some day be applied to phenomena of the real world.

Quantisations of Ordered *-Spaces
Aurelian Gheondea, Bilkent University
An ordered *-space is a complex vector space endowed with an involution and a strict cone, with certain compatibility conditions. A quantisation of an ordered *-space Z is a sequence of strict cones in M_n(Z), the tensor product of the C*-algebra of n x n complex matrices with Z, with certain compatibility conditions. We show that to any ordered *-space one ...Detay »

4-boyutlu farklı metrik işaretli manifoldlar üzerindeki reküran tensör alanları
Bahar Kırık, Marmara Üniversitesi
Bu konuÅŸmada, (+, +, -, -), (+, +, +, -) ve (+, +, +, +) metrik iÅŸaretlerine sahip 4-boyutlu manifoldlar üzerindeki ikinci mertebeden simetrik ve anti-simetrik olan tensör alanlarından bahsedilecektir. Ä°lk olarak, 4-boyutlu manifoldlar üzerindeki bazı geometrik yapılar hakkında bilgi verilecektir. Daha sonra, reküran tensör alanları incelenecekt...Detay »

On an algebraic definition of the Boy surface.
François Apery, Université de Haute Alsace
In 1984, I was able to obtain a parametrization of the Boy surface by eliminating the Whitney umbrellas of the Steiner surface using the so-called hyperbolic confluence of pairs of singularities. As a result, the Boy surface appears to be a real algebraic surface of degree six. However, the construction was a mix of geometry, differential topology and singu...Detay »

In silico Biyoloji: Omik Teknolojilerden Sentetik Biyolojiye
Şule Arı, İstanbul Üniversitesi
Günümüzde yaÅŸam bilimlerinde ve moleküler biyolojideki hızlı veri birikimi, bulguların analizinde matematiksel yaklaşımların kullanımını artırmıştır. Genotip-fenotip iliÅŸkisinin aydınlatılmasına odaklanmış olan yaÅŸam bilimleri 2000’li yıllardan itibaren geliÅŸen süreçteki olaÄŸanüstü ilerlemeyi, Ä°nsan Genom Projesi’nin önÃ...Detay »

Coverings and actions of internal groupoids within the category of groups with operations
H. Fulya Akız, Yozgat Bozok Üniversitesi
Groupoids are mathematical structures that have proved to be useful in many areas of science. A groupoid is a small category in which each arrow has an inverse and a group-groupoid is an internal groupoid in the category of groups. It is known that if $X$ is a topological group, then the fundamental groupoid $\pi_1 X$ is a group groupoid. Then the catego...Detay »

Exact and asymptotic enumeration of integer partitions
Jehanne Dousse, Universität Zürich
A partition of n is a non-increasing sequence of positive integers whose sum is n. Though their definition is easy to state, partitions are very difficult to count, and no simple formula is known for their number. However, it is possible to obtain nice asymptotics formulas. This was first done by Hardy and Ramanujan using the circle method, which relies ...Detay »

Fine structure constant and Why Atiyah was wrong about it
Bayram Tekin, ODTÜ
Atiyah just proposed an explanation for the number 137 that plays a major role in Nature and every matter we see around. I will explain why his approach is bound to fail.Detay »

t-Spread Monomial Ideals
Ayesha Asloob Qureshi, Sabancı Üniversitesi
We introduce the concept of t-spread monomials and t-spread strongly stable ideals. These concepts are a natural generalization of strongly stable and squarefree strongly stable ideals. For the study of this class of ideals we use the t-fold stretch- ing operator. It is shown that t-spread strongly stable ideals are componentwise linear. Their height, th...Detay »

Dynamical and Geometrical Structures of Curl Forces
Partha Guha, S.N. Bose National Centre for Basic Sciences
We give a gentle introduction to the Hamiltonian formalism of curl forces, introduced by Berry and Shukla and show its application to non-central forces and dynamics related to saddle potentials. We demonstrate its connection with the cofactor systems introduced by the Linköping school. We impose gyroscopic and frictional type forces on the existing curl f...Detay »
