A Nullstellensatz for amoebas
The amoeba of an affine algebraic variety V ⊂ (C∗)r is the image of V under the map (z1, . . . , zr) 7→ (log |z1|, . . . , log |zr|). We give a characterisation of the amoeba based on the triangle inequality, which we call ‘testing for lopsidedness’. We show that if a point is outside the amoeba of V , there is an element of the defining ideal which witnesses this fact by being lopsided. This c...
متن کاملA COMMUTATIVITY CONDITION FOR RINGS
In this paper, we use the structure theory to prove an analog to a well-known theorem of Herstein as follows: Let R be a ring with center C such that for all x,y ? R either [x,y]= 0 or x-x [x,y]? C for some non negative integer n= n(x,y) dependingon x and y. Then R is commutative.
متن کاملA Tropical Nullstellensatz
We suggest a version of Nullstellensatz over the tropical semiring, the real numbers equipped with operations of maximum and summation.

متن کاملA Bound for Orders in Differential Nullstellensatz
We give the first known bound for orders of differentiations in differential Nullstellensatz for both partial and ordinary algebraic differential equations. This problem was previously addressed in [1] but no complete solution was given. Our result is a complement to the corresponding result in algebraic geometry, which gives a bound on degrees of polynomial coefficients in effective Nullstelle...
