<br>Zaman : 20 Kasim 2009 Cuma, 11:00<br><br>Oz:<br>Contrary to the graded algebra case, very little is known about the Hilbert functions of local rings. Rossi conjectured that every one-dimensional Gorenstein local ring has a nondecreasing Hilbert function. This conjecture is open even for Gorenstein local rings corresponding to monomial curves. In this talk, I will present some partial results supporting Rossi’s conjecture in the Gorenstein monomial curve case. These results based on the tool of gluing provide infinitely many families of Gorenstein monomial curves with the corresponding local Gorenstein rings having nondecreasing Hilbert functions.<br>
