Titlul prezentării: Security of digital signatures in the post-quantum epoch

ABSTRACT. I will delve into the pressing challenges posed by the rise of quantum computing to classical digital signatures, with a particular focus on RSA. Shor's algorithm threatens the security of traditional public-key cryptography by efficiently factoring large numbers. In response to this threat, the presentation explores post-quantum digital signature schemes anchored in hashing techniques, renowned for their resilience to quantum attacks. A central aspect of this exploration is the introduction and utilization of the Verkle Tree, an innovative data structure, in the development of electronic signatures. Not only does the Verkle Tree enhance security, but it also boosts efficiency in the post-quantum landscape, providing a practical defense against quantum threats. Moreover, I will talk about post-quantum design concepts that leverage the Verkle Tree, offering insights into its integration into broader cryptographic protocols.

Titlul prezentării: Cosmological observational constraints on the power law f(Q) type modified gravity theory

ABSTRACT. In this talk, I will discuss an alternative mathematical framework for advancing our understanding of dark energy beyond the confines of standard General Relativity (GR), within the realm of f(Q) modified gravity theory. The discussion commences with a succinct overview of the dark energy enigma, followed by an examination of the fundamental elements that provide opportunities for modifying or extending GR to address current challenges. To comprehensively grasp the accelerated expansion phenomenon of the universe, we will delve into a power-law type f(Q) cosmological model. After that, this model will confront observational datasets through statistical analysis, contrasting it with the ΛCDM model. Additionally, a detailed comparison between the predictions of the power-law model and the ΛCDM model through various cosmological applications will be presented. Later on, I will conclude the findings by demonstrating how the f(Q) model remains capable of elucidating current observational results related to cosmological parameters, providing a compelling and coherent explanation for the accelerating expansion of the Universe, albeit with distinctions from the ΛCDM paradigm. We will finish off by discussing some future perspectives.

Titlul prezentării: KEY RESULTS AND RECENT ADVANCES IN DYNAMIC
GEOMETRY

ABSTRACT. Dynamic geometry is primarily concerned with processes
defined in the complex plane, in which, starting from a given configuration F0 and a sequence of transformations (Tn)n≥0, one obtains the configuration Fn+1 by applying the transformation Tn to shape Fn, that is Fn+1=Tn(Fn). Several questions now arise: 

1) Can we find the exact shape after n iterations? 
2) Does the sequence (Fn)n≥0 converge to a fixed configuration? 
3) Does (Fn)n≥0 converge to a fixed shape? 
4) If convergent, can we identify the limit of (Fn)n≥0? 
5) Can we recover the initial configuration based on the configuration obtained after n steps the information on the iterations (Tn)n≥0, and?
These questions will be discussed in the context of simple but surprising triangle iterations, like the dynamic geometries generated by Kasner triangles, the bisector triangle, or by cevians defined with points located on the power curve.
