Robbiano, Lorenzo Hyperplane sections, Gröbner bases, and Hough transforms. (English) Zbl 1311.13041 J. Pure Appl. Algebra 219, No. 6, 2434-2448 (2015). This paper is about hyperplane sections of affine schemes. It is shown that under certain assumptions a Gröbner bases of a scheme is closely related to Gröbner bases of the scheme’s hyperplane sections (Theorems 1.7 and 1.10). This was known in the homogeneous case, and this paper deals with the inhomogeneous case. It is shown how these results can be used to reconstruct schemes from enough hyperplane sections. This technique may have applications for example in implicitization (which can be much easier in hyperplane sections). The second part of the paper extends the results to parametrized families of schemes. This, in turn, may have applications in tomography, where one may want to reconstruct the shape of an organ from MRI data.
