Rationality problem of three-dimensional purely monomial group actions: the last case
A k-automorphism σ of the rational function field k(x1, . . . , xn) is called purely monomial if σ sends every variable xi to a monic Laurent monomial in the variables x1, . . . , xn. Let G be a finite subgroup of purely monomial k-automorphisms of k(x1, . . . , xn). The rationality problem of the G-action is the problem of whether the G-fixed field k(x1, . . . , xn) G is k-rational, i.e., pure...
متن کاملDeterminantal ideals and monomial curves in the three-dimensional space
We show that the defining ideal of every monomial curve in the affine or projective three-dimensional space can be set-theoretically defined by three binomial equations, two of which set-theoretically define a determinantal ideal generated by the 2-minors of a 2× 3 matrix with monomial entries.
متن کاملNegative solutions to three-dimensional monomial Noether problem
Three-dimensional monomial Noether problem can have negative solutions for 8 groups by the suitable choice of the coefficients. We find the necessary and sufficient condition for the coefficients to have a negative solution. The results are obtained by two criteria of irrationality using Galois cohomology.
متن کاملPurely absorptive fifth-order three-dimensional electronic spectroscopy.
We demonstrate a method to measure a purely absorptive fifth-order three-dimensional (3D) electronic spectrum based on a pulse-shaper assisted pump-probe beam geometry setup. The 3D spectra are measured as a function of two independently controlled population times. With phase-cycling and data processing, purely absorptive 3D spectra of chlorophyll a are obtained.
متن کاملThe Rationality Problem for Three- and Four-Dimensional permutational Group Actions
Assume that K is a field, containing the full group of 4th roots of unity μ4, and char K = 2, 3. Let G be a finite non-abelian subgroup of GLn(K) for n = 3 or n = 4. The group G induces an action on K(x1, . . . , xn), the rational function field of n variables over K. Consider groups represented by matrices such that in each row and column there is exactly one element from μ4 and all other elem...
