Symbolic Rees Algebras,We survey old and new approaches to the study of symbolic powers of ideals. Our focus is on the symbolic Rees algebra of an ideal, viewed both as a tool to investigate its symbolic powers and as a source of challenging problems in its own right. We provide an invitation to this area of investigation by stating several open questions.

Depth Functions and Symbolic Depth Functions of Homogeneous Ideals,We survey recent studies and results on the following problem: for which function . does there exist a homogeneous ideal . in a polynomial ring . such that (a) depthS∕Q. = .(.) for all . ≥ 1, or (b) depthS∕Q. = f(t) for all . ≥ 1?

Applications of Differential Graded Algebra Techniques in Commutative Algebra,Differential graded (DG) algebras are powerful tools from rational homotopy theory. We survey some recent applications of these in the realm of homological commutative algebra.

Our analysis involves tools from algebraic geometry (Segre-Veronese varieties), classical commutative algebra (Buchsbaum-Eisenbud criteria for exactness, Hilbert-Burch theorem), and homological algebra (Koszul homology, spectral sequences). We treat in detail the c

,‘Falcons’ and ‘Witches’: Flyers,function. Our intended audience are Commutative Algebraists who may be new to interpolation problems. In particular, the main aim of our presentation is to provide a self-contained proof containing all details (including some we could not find in the literature). Also, considering our intended audie

https://doi.org/10.1007/978-1-349-09694-7property that is conjectured to hold for certain classes of rings but fails in general. We discuss bounds on degrees of syzygies and regularity given partial information about the beginning of a free resolution, such as degrees of generators or degrees of first syzygies. We also focus specifically o
