Recently, Peeva and the second author constructed irreducible projective varieties with regularity much larger than their degree, yielding counterexamples to the Eisenbud-Goto Conjecture. Their construction involved two new ideas: Rees-like algebras and step-by-step homogenization. Yet, all of these varieties are singular and the nature of the geometry of these projective varieties was left open. The purpose of this paper is to study the singularities inherent in this process. We compute the codimension of the singular locus of an arbitrary Rees-like algebra over a polynomial ring. We then show that the relative size of the singular locus can increase under step-by-step homogenization. To address this defect, we construct a new process, we call prime standardization, which plays a similar role as step-by-step homogenization but also preserves the codimension of the singular locus. This is derived from ideas of Ananyan and Hochster and we use this to study the regularity of certain smooth hyperplane sections of Rees-like algebras, showing that they all satisfy the Eisenbud-Goto Conjecture, as expected. On a more qualitative note, while Rees-like algebras are almost never Cohen-Macaulay and never normal, we characterize when they are seminormal, weakly normal, and, in positive characteristic, F-split. Finally, we construct a finite free resolution of the canonical module of a Rees-like Algebra over the presenting polynomial ring showing that it is always Cohen-Macaulay and has a surprising self-dual structure.2010 Mathematics Subject Classification. 13D02,14B05. 1 2 P. MANTERO, J. MCCULLOUGH, AND L. E. MILLER or even some mildly singular varieties. There are many cases where the conjecture does hold including the case of curves [8] and smooth surfaces in characteristic 0 [21,13], and certain 3-folds in characteristic 0 [22]. See also related work of Kwak-Park [12] and Noma [19]. There are also mild classes of singular surfaces for which Equation (1) holds, see [17].The process in [16] of constructing the examples of projective varieties failing Equation (1) involves two major steps. The first step is the construction of the Reeslike algebra, which defines a subvariety of a weighted projective space. Specifically, given a homogeneous ideal I in a polynomial ring S over a field k, the Reeslike algebra of I is the non-standard graded k-algebra RL(The second step, which applies to any homogeneous ideal in a non-standard graded polynomial ring, produces an associated ideal in a much larger polynomial ring called its step-by-step homogenization. Unlike the usual homogenization of an ideal which defines the projective closure of an affine variety, the step-by-step homogenization produces a much larger variety; however, it preserves graded Betti numbers and primeness for nondegenerate primes, making it sufficient to produce the counterexamples to Equation (1).Thus far, explicit understanding of the geometry of the processes involved in both of these two steps is lacking. It was proved in [16] that Rees-like algebras are no...
