Superpowered Modular Forms: Level Up Your Symmetries!
This paper proves the automorphy of the symmetric power lifting Sym^n f for all n ≥ 1, where f is a cuspidal Hecke eigenform without complex multiplication. This removes a prior assumption requiring the absence of supercuspidal primes. The proof relies on a new automorphy lifting theorem and a refined "killing ramification" technique.

Inaccessibility to a broader audience
The paper heavily relies on specialized mathematical concepts and notations, making it very difficult for anyone outside of the niche field of automorphic forms to understand. It assumes deep familiarity with Langlands functoriality, Galois representations, and advanced algebraic number theory.
Heavy dependence on prior work
The paper builds upon prior work by the authors and others, referencing it extensively. Without access to and understanding of these prerequisite papers (e.g. [NT21], [BLGGT14], [KW09a]), evaluating the current work's originality and significance is extremely challenging.
Technical complexity of the core proof idea
The "killing ramification" technique, while central to the proof, is presented quite technically. The introduction of "seasoned" automorphic representations adds another layer of complexity. A clearer, more intuitive explanation of this core idea would improve the paper's impact.
Rating Explanation
This paper makes a significant contribution to the field of automorphic forms by removing a key assumption from prior work on symmetric power functoriality for holomorphic modular forms. While highly technical and specialized, it presents a novel automorphy lifting theorem and an intricate proof. The impact is primarily within the specialized field, hence the rating of 4 rather than 5.
