What is the time complexity of multiplying two n x n matrices using the fastest known asymptotically optimal algorithm as of 2024, and what is the name of that algorithm?
O(n^2.3719) using the Coppersmith–Winograd-like algorithms, more specifically the algorithm by Alman and Vassilevska Williams (2020), which improved upon earlier bounds.

In quantum field theory, how does the concept of renormalization resolve the divergence issues in quantum electrodynamics (QED), and what role does the running coupling constant play?
Renormalization absorbs the infinities that appear in QED (like in loop diagrams) into redefined physical constants (mass, charge). The running coupling constant describes how the effective interaction strength (e.g., electric charge) changes with energy scale due to vacuum polarization effects, and is governed by the renormalization group equations.

What is the theoretical minimum number of samples required to PAC-learn a concept class C under the Probably Approximately Correct (PAC) model, and how does this relate to the VC dimension of the class?
O(εVC(C)+log(1/δ))
where VC(C) is the Vapnik–Chervonenkis dimension of the concept class C. The VC dimension measures the capacity (complexity) of the hypothesis space — it quantifies the largest set of points that can be shattered (i.e., classified in all possible ways) by functions in C. This result shows that generalization in learning is fundamentally governed by the complexity of the hypothesis space, not just training performance
