Zero-cycles on products of elliptic curves over p-adic fields
Here we study zero-dimensional subschemes of ruled varieties, mainly Hirzebruch surfaces and rational normal scrolls, by applying the Horace method and the Terracini method
Let be a bounded strictly pseudoconvex domain in and let be a positive divisor of with finite area. We prove that there exists a bounded holomorphic function such that is the zero set of . This result has previously been obtained by Berndtsson in the case where is the unit ball in .
Given an o-minimal expansion ℳ of a real closed field R which is not polynomially bounded. Let denote the definable indefinitely Peano differentiable functions. If we further assume that ℳ admits cell decomposition, each definable closed subset A of Rⁿ is the zero-set of a function f:Rⁿ → R. This implies approximation of definable continuous functions and gluing of functions defined on closed definable sets.
We propose a refinement of the notion of blow-Nash equivalence between Nash function germs, which has been introduced in [2] as an analog in the Nash setting of the blow-analytic equivalence defined by T.-C. Kuo [13]. The new definition is more natural and geometric. Moreover, this equivalence relation still does not admit moduli for a Nash family of isolated singularities. But though the zeta functions constructed in [2] are no longer invariants for this new relation, thanks to a Denef & Loeser...
In the first part of the article the proof of the following theorem is given: Let point be the middle of in the triangle , point the intersection of and the axis of angle , point the foot of the perpendicular from on . If angles are equal, then the angle is the right one. In the second part, the area of right angle triangle using only the length of the axis of the right angle and of the median is derived.
