🎉 Bittersweet News from the Math Department! 🎉

Please join us in celebrating our amazing Office Coordinator, M’Tia Williams, as she begins an exciting new chapter! 💼✨

After serving as the heart of the SU Mathematics Department—keeping the office running smoothly, supporting students and faculty, and yes, even managing this very social media account—M’Tia is heading to the Whitman School of Management as their newest Academic Advisor! 📚👏

While we’ll deeply miss her warmth, creativity, and leadership here in Math, we are so proud of all she’s accomplished and excited for what’s ahead.

Congratulations, M’Tia! Thank you for everything—you’ve left your mark, and your Math family will always be rooting for you. 💙

Speaker: Oana Veliche of Northeastern University
Title: On a construction of a minimal free resolutions of the residue field of a codepth 3 local ring

Abstract: In a paper with Van Nguyen we gave a description of a truncated minimal free resolution, up to homological degree five, of the residue field k over any local Noetherian ring (R,m,k) of any codepth. This description relies on the graded commutative algebra structure of the Koszul homology A=H(K), where K is the Koszul complex of the maximal ideal. The free resolution is given as building blocks in terms of the Koszul complex K. In a subsequent paper we constructed the entire free resolution of the residue field over a complete intersection ring, using an iterated mapping cone construction.

In my talk, I will discuss how the mapping cone construction in general can yield a minimal free resolution of k over other classes of rings. In particular, for local ring (R,m,k) of class T of codepth 3 (that is part of the Weyman and Avramov-Kustin-Miller classification), we construct a graded resolution of k over A and then from it we obtain the minimal free resolution of k over R.

Title: Rigidity of free boundary minimal surface disks in mean convex three-manifolds

Abstract: In this lecture, we present a local rigidity result for free boundary minimal two-disks strictly stable on a Riemannian three-manifolds with a positive lower bound on its scalar curvature and mean convex boundary. Assuming that image001.png locally maximizes the modified Hawking mass, we prove that a neighborhood of it in image002.png is isometric to one half de Sitter Schwarzschild space. This is a joint work with Barnabé Lima (UFPI) and João Silva (UFPI).
