Quantum Speedup for Some Geometric 3SUM-Hard Problems and Beyond
The classical 3SUM conjecture states that the class of 3SUM-hard problems does not admit a truly subquadratic $O(n^{2-δ})$-time algorithm, where $δ>0$, in classical computing. The geometric 3SUM-hard problems have widely been studied in computational geometry and recently, these problems have been examined under the quantum computing model. For example, Ambainis and Larka [TQC'20] designed a quantum algorithm that can solve many geometric 3SUM-hard problems in $O(n^{1+o(1)})$-time, whereas Bu…

MACM: Utilizing a Multi-Agent System for Condition Mining in Solving Complex Mathematical Problems
Recent advancements in large language models, such as GPT-4, have demonstrated remarkable capabilities in processing standard queries. Despite these advancements, their performance substantially declines in \textbf{advanced mathematical problems requiring complex, multi-step logical reasoning}. To enhance their inferential capabilities, current research has delved into \textit{prompting engineering}, exemplified by methodologies such as the Tree of Thought and Graph of Thought. Nonetheless, the…

Classical Grand Angular Momentum in N-Body Problems
The concept of grand angular momentum is widely used in the study of N-body problems quantum mechanically. Here, we applied it to a classical analysis of N-body problems. Utilizing the tree representation for Jacobi and hyperspherical coordinates, we found a decomposition of its magnitude into magnitudes of one-body angular momenta in 3 dimensions. We generalized some results from the two-body problem. Furthermore, we derive the general expression for the scattering angle for the N-body problem.

As I came of age in the mid 70s, I "learned" that the markets drove innovation and provided solutions - while government was "the problem". WHen I look at utilities I see the opposite - rent seeking, and a failure to copy - not even invest in R&D, just copy - demonstrated solutions to problems. Maybe we need to rethink the role of private utilities? Because they seen incapable of solving the critical problems we face, while charging more and more to replace infras…
