Formality, Alexander Invariants, and a Question of Serre
We elucidate the key role played by formality in the theory of characteristic and resonance varieties. We show that the I-adic completion of the Alexander invariant of a 1-formal group G is determined solely by the cup-product map in low degrees. It follows that the germs at the origin of the characteristic and resonance varieties of G are analytically isomorphic; in particular, the tangent con...
متن کاملJacobians among Abelian Threefolds: a Formula of Klein and a Question of Serre
Let k be a field and f be a Siegel modular form of weight h ≥ 0 and genus g > 1 over k. Using f , we define an invariant of the k-isomorphism class of a principally polarized abelian variety (A, a)/k of dimension g. Moreover when (A, a) is the Jacobian of a smooth plane curve, we show how to associate to f a classical plane invariant. As straightforward consequences of these constructions when ...
متن کاملNotes on Serre fibrations
Here the solid arrows represent maps that are given, and the problem is to find a map h commuting in the diagram. Usually the map i is an inclusion, and p is some kind of “bundle map” such as a local product. Note the special cases: (i) if i is an inclusion, E = A, and f = 1A, then the extension problem asks whether A is a retract of X; and (ii) if p is surjective, X=B, and g = 1B, the lifting ...
متن کاملOn a Lemma of Deligne-Serre
This note is intended to provide the group-theoretic machinery for associating complex representations to certain modular forms. We recall [DS] that to a Hecke eigenform of weight 1 on GL2, we can associate a 2-dimensional compatible system of λ-adic representations. Rankin’s method shows that “on average” the eigenvalues of Frobenius are of O(1), and by a group-theoretic argument ([DS] §§7-8),...
متن کاملthe impact of training on second language writing assessment: a case of raters’ biasedness
چکیده هدف اول این تحقیق بررسی تأثیر آموزش مصحح بر آموزش گیرندگان براساس پایایی نمره های آنها در پنج بخش شامل محتوا ، سازمان ، لغت ، زبان و مکانیک بود. هدف دوم این بود که بدانیم آیا تفاوتهای بین آموزشی گیرندگان زن و مرد در پایایی نمرات آنها وجود دارد. برای بررسی این موارد ، ما 90 دانشجو در سطح میانه (متوسط) که از طریق تست تعیین سطح شده بودند انتخاب شدند. بعد از آنها خواستیم که درباره دو موضوع ا...
