چکیده
Abstract In this paper, we prove a classification theorem for the zero sets of real analytic Beltrami fields. Namely, show that set field on analytic, connected 3-manifold without boundary is either empty after removing its isolated points or can be written as countable, locally finite union differentiably embedded, 1-dimensional submanifolds with (possibly empty) and tame knots. Further, consider question how complicated these knots possibly be. To end, standard (open) solid toroidal annulus in $${\mathbb {R}}^3$$ R3 , there exist any pair ( p q ) positive, coprime integers countable infinitely many distinct metrics such each metric, exists field, corresponding to eigenvalue $$+1$$ xmlns:mml="http://www.w3.org/1998/Math/MathML">+1 curl operator, whose precisely given by )-torus knot. The fields are constructed explicitly down Cartesian coordinates means elementary functions alone.

Real Closed Fields with Nonstandard Analytic Structure
We consider the ordered field which is the completion of the Puiseux series field over R equipped with a ring of analytic functions on [−1, 1]n which contains the standard subanalytic functions as well as functions given by tadically convergent power series, thus combining the analytic structures from [DD] and [LR3]. We prove quantifier elimination and o–minimality in the corresponding language...

متن کاملFields with Analytic Structure
We present a unifying theory of fields with certain classes of analytic functions, called fields with analytic structure. Both real closed fields and Henselian valued fields are considered. For real closed fields with analytic structure, o-minimality is shown. For Henselian valued fields, both the model theory and the analytic theory are developed. We give a list of examples that comprises, to ...
متن کاملComputing Beltrami Fields
Abstract. For solving the non-linear equations governing force-free fields, an iterative methodology based on the splitting of the problem is described. On the basis of this splitting, three families of subproblems have to be solved numerically. The first problem consists to find a potential field. A mixed hybrid method is used to solve it. The second problem, which is a curl-div system, is sol...
