What is a "non-trivial" example of a commutative algebraic group over $\mathbb{C}$?

Let $G$ be a commutative connected algebraic group over $\mathbb{C}$. A theorem of Serre says that there exists an exact sequence $$1\to \mathbb{G}_a^n\times \mathbb{G}_m^m\to G\to A\to 1,$$ where $A$ …

Is there a proof of Hodge theory using condensed mathematics?

As is well known, many results in complex geometry "feel" algebraic (and often have statements which are "completely algebraic") but only have "transcendental" proofs (i.e., using analysis in some ess …
