The Commutative Algebra


The Commutative Algebra of Singularities in Birational Geometry: Multiplier Ideals, Jets, Valuations, and Positive Characteristic Methods

Month: May 2013
Date: May 6--10
Name: The Commutative Algebra of Singularities in Birational Geometry: Multiplier Ideals, Jets, Valuations, and Positive Characteristic Methods
Location: Mathematical Sciences Research Institute, Berkeley, California.

Description

The workshop will examine the interplay between measures of singularities coming both from characteristic p methods of commutative algebra, and invariants of singularities coming from birational algebraic geometry. There is a long history of this interaction which arises via the "reduction to characteristic p" procedure. It is only in the last few years, however, that very concrete objects from both areas, namely generalized test ideals from commutative algebra and multiplier ideals from birational geometry, have been shown to be intimately connected. This workshop will explore this connection, as well as other topics used to study singularities such as jets schemes and valuations.

IB Mathematics HL– Calculus, Differentiation, Related rates, Rate of change


How can we solve the following related rates word problem?
“A 10-metres ladder is leaning against a vertical wall. The foot of the ladder slips away from the wall at the rate of 0.1 meter per minute. How fast is the top of the ladder sliding down the wall when the top is 4 meters above the ground?”

Math and Music Enthrall at MAA Distinguished Lecture


When St. Mary’s College of Maryland mathematics professor David Kung heard a public radio story about a presentation devoted to math and music, he took issue with the presentation’s title.
The seminar was called "Math and Music—Closer Than You Think," but, as Kung told a packed auditorium at the Carnegie Institution for Science on February 26, he already regarded the two disciplines as "epsilon apart."
