Analysis of Agent-Based Simulation Models through Metamodeling
Mert Edalı, Yıldız Technical University

We propose a three-stage analysis procedure to interpret input-output relationships of agent-based simulation models. In the first stage, we use metamodels of agent-based models to approximate the input-output dynamics by constructing a functional relationship. For this purpose, we employ Random Forest technique from machine learning domain. Based on the res...Detay »

Conformal Twisted Products
Sibel Gerdan Aydın, İstanbul Üniversitesi

We introduce the notion of conformal twisted product submanifolds of the form $M ={} _fM^T \times {}_bM^\theta$ and $M ={}_fM^\theta \times {}_bM^T$, where $M^T$ is a holomorphic submanifold and $M^\theta$ is a proper slant submanifold of $M$ in a locally conformal Kaehler manifold. We give an illustrative example such submanifolds and we give necessary an...Detay »

On Domination Number of Cayley Graphs
Sibel Özkan, Gebze Technical University

A dominating set of a graph $\Gamma$ is a subset $D$ of $V$, such that every vertex not in $D$ is adjacent to at least one member of $D$. The domination number $\gamma(\Gamma)$ is the minimum cardinality of a dominating set for $\Gamma$. The problem of determining the minimum number of queens that can be placed on a chessboard so that all squares are either ...Detay »

Quiver Representations II
Emre Coşkun, ODTÜ

In this series of talks, we shall introduce quivers and their representations and discuss their basic properties. We shall also discuss and prove (if time permits) Gabriel's theorem, which gives a complete classification of quivers of finite type.Detay »

Traces and Determinants on noncommutative algebras and countable groups
(on the Occasion of Pr ...
Georges Skandalis, Paris VII, Institut de Mathematiques de Jussieu

Elek and Szabo established Luck’s deteminant conjecture for (Gromov’s) soc groups. We will present a work in collaboration with G. Balcı in which we give an equivalent definition of soc groups and a slightly different proof of this conjecture in terms of traces on the free group algebra. Most of the talk will be spent on explaining and illustrating ...Detay »
