As a non-binary person living in #Bergen, #Norway, this video made me cry from pure euphoria, a wave of relief knowing I am seen just as I am.
I hope it brings you the same confidence and happiness, showing that you are truly seen and celebrated for who you are.

Optimal Threshold Signatures in Bitcoin
We formulate the design of a threshold signature scheme as made possible on cryptocurrency protocols like Bitcoin. The funds are secured by an m-of-n threshold signature, where at least m signatures are needed to unlock the funds. A user designs this scheme knowing that a malicious attacker can also obtain the signatures with some probability. Higher thresholds offer more security, but also risk locking the user out of his own funds. The optimal threshold balances these twin effects. Interventi…

Think in Games: Learning to Reason in Games via Reinforcement Learning with Large Language Models
Large language models (LLMs) excel at complex reasoning tasks such as mathematics and coding, yet they frequently struggle with simple interactive tasks that young children perform effortlessly. This discrepancy highlights a critical gap between declarative knowledge (knowing about something) and procedural knowledge (knowing how to do something). Although traditional reinforcement learning (RL) agents can acquire procedural knowledge through environmental interaction, they often operate as bla…

Transformers Can Learn Connectivity in Some Graphs but Not Others
Reasoning capability is essential to ensure the factual correctness of the responses of transformer-based Large Language Models (LLMs), and robust reasoning about transitive relations is instrumental in many settings, such as causal inference. Hence, it is essential to investigate the capability of transformers in the task of inferring transitive relations (e.g., knowing A causes B and B causes C, then A causes C). The task of inferring transitive relations is equivalent to the task of connecti…

Ein wohnungsloses Känguru in Berlin? Hmm, das hatten wir doch schon mal. Ist es gar kommunistisch und war in Vietnam?

Hüpft Jakob Augsteins Känguru durch Berlin?
In der Hauptstadt ist ein Känguru ausgebüxt – angeblich aus dem Hause von Jakob Augstein. Nun muss es sich wohl mit dem Berliner Wohnungsmarkt rumschlagen.

Constructing Jacobians of rank 1
Let $K$ be a number field, let $g \geq 1$ be an integer and let $f(x) = (x - a_1) \cdots (x - a_{2g + 1}) \in O_K[x]$ be a polynomial that splits into $2g + 1$ distinct linear factors. Write $C$ for the hyperelliptic curve given by $C: y^2 = f(x)$ and write $J = \mathrm{Jac}(C)$ for its Jacobian. Under mild technical assumptions on $f$ that are satisfied almost always, we prove that there exists some $d \in K^\times$ such that the quadratic twist $J^d$ has rank exactly equal to $1$. As a conseq…
