By choosing a basis of as a 1-dimensional L-vector space, we thereby identify Z Q !Lie(A) with the natural inclusion of Linto C, and in this way is commensurable with the ring of integers of Linside L. Hence, Ais L-linearly isogenous to C =O L. Thus, the L-linear isogeny class of the abelian variety Ais determined by the eld Land the choice of

Groebner Bases and Coding - ICIT 2021

A Groebner basis (according to Bruno Buchberger, 1965) or a standard basis (according to Heisuke Hironaka, 1964) is a finite generating set of an ideal in the polynomial ring = [ 1, , ] over a field For any such ideal the (reduced) Groebner basis is unique and can be determined algorithmically.

literature speaks almost entirely in terms of the constraints whereas the algebra can be expressed more invariantly in terms of the ideal gener­ ated by the constraints. We work entirely over the reals R as our ground field, although any field of characterisitic 0 would do and the complex numbers C are more common in certain physical applications.

In other words, an element of EP 2m evaluated on projective varieties can be bounded in terms of Betti numbers if and only if it is a linear combination of the Euler number and the signature.

A Conspiracy Argument for OptimalityTheory: Emakhuwa

In some Emakhuwa speech varieties, H tones appear in the surface just where they are located in the input. In GP terms, these dialects (largely) lack any tonal rules. This paper focuses on three dialects where GP would require the formulation of rules to account for differences between surface forms and phonological inputs.
