These notes introduce a new class of algebraic curves on Hilbert modular surfaces. These curves are called twisted Teichmüller curves, because their construction is very reminiscent of Hirzebruch-Zagier cycles. These new objects are analyzed in detail and their main properties are described. In particular, the volume of twisted Teichmüller curves is calculated and their components are partially classified. The study of algebraic curves on Hilbert modular surfaces has been widely covered in the literature due to their arithmetic importance. Among these, twisted diagonals (Hirzebruch-Zagier cycles) are some of the most important examples.

Abstract The progress in the field of 3D integration of microeletronic systems enables a dependable and cost-effective density increase of ICs in a single package. The possibility to closely integrate heterogeneous ICs with different technologies and functionalities opens a way out of the “Memory/Processor Gap” via integration of scalable 3D stacked DRAMs with very high communication bandwidths and the corresponding logic (e. g. memory controller). In this way 3D integration of standard DRAMs with MPSoCs can largely improve the energy efficiency and increase the memory bandwidth.

The paper explores the concept of predatory trading and its role in the collapse of Long-Term Capital Management (LTCM) in 1998. It addresses the mechanisms behind predatory trading, its consequences, and potential preventive measures. The analysis includes a theoretical framework for understanding predatory trading dynamics, followed by an examination of its advantages and disadvantages. Through this exploration, the paper aims to provide insights into the behavior of market participants during crises and the implications for financial stability.

Exploring the relationship between brand value and financial performance, this thesis examines the significance of annual rankings produced by consultancies like Interbrand and Brand Finance. It highlights how these rankings influence companies' popularity and market perception. The research focuses on Interbrand's 2006 list of the world's most valued brands, revealing insights into brand equity's impact on business success. The study aims to understand whether a strong brand correlates with improved financial outcomes, providing a critical analysis relevant to both academics and practitioners in business economics.

The exploration of entrepreneurship within business sciences is a relatively new yet rapidly evolving field. This thesis highlights the significant growth in research over recent decades, which has generated various theories and concepts. Despite this progress, many gaps remain, particularly regarding the most effective ways for politicians to promote entrepreneurship and the identification of key entrepreneurial skills and their acquisition. The work emphasizes the need for further investigation into these areas to enhance understanding and support for entrepreneurial ventures.
