The Taylor-Wiles construction and multiplicity one. (English) Zbl 0916.11037
The author revisits the Taylor construction, which is a key element in Wiles’ proof of the modularity of elliptic curves. He shows that one can dispense with the usual multiplicity one theorems derived from \(q\)-expansions, and even recover them with different proofs. This is derived from a refinement of the commutative algebra estimates of Wiles and Lenstra. As an application he treats Wiles-Taylor, and also an example of Shimura curves where no \(q\)-expansion is available.
