A note on joint reductions and mixed multiplicities

D Viet, L Dinh, T Thanh - Proceedings of the American Mathematical …, 2014 - ams.org
Let $(A,\frak m) $ be a noetherian local ring with maximal ideal $\frak {m} $ and infinite

On Some Superficial Sequences.

NT Manh, TTH Thanh - Southeast Asian Bulletin of …, 2014 - search.ebscohost.com
The paper proves that the superficial sequences in [13, 15, 16, 25] are the weak-(FC)-
sequences in [18]. This follows that [18, Theorem 3.4] of Viet in 2000 covers the results of …

Mixed Multiplicities of Maximal Degrees (J. Korean Math. Soc. 55 (2018), No. 3, 605-622)

TTH Thanh, DQ Viet - arXiv preprint arXiv:1906.01985, 2019 - arxiv.org
The original mixed multiplicity theory considered the class of mixed multiplicities concerning
