Provost Lecture Series: Math professor shares steepest descent method

9/2/2011

Dr. Ben Ntatin, associate professor of mathematics, will be the next featured speaker in the Provost Lecture Series at 3 p.m., Thursday, Sept. 8 in the Morgan University Center, Room 303.

For many people, understanding complex mathematical equations and concepts is more difficult than walking in the mountains. Somehow, however, an Austin Peay State University mathematics faculty member makes the ideas relate.

Dr. Ben Ntatin, associate professor of mathematics, will present the next session in the weekly Provost Lecture Series at 3 p.m., Thursday, Sept. 8 in the Morgan University Center, Room 303. The title of his presentation is “Walking in the mountains: The steepest descent method.”

His talk will be about how the notion of linearity is fundamental for numerous considerations in mathematics and engineering science.

“In rough terms, if a problem is linear or can be well approximated by a linear model, then there may very well be standard means of approaching it,” he said. “Most physically significant problems can be modeled into partial differential equations, and in the talk, I would demonstrate how such problems could be reduced into a large matrix equation, for which the steepest descent method is appropriate.”

Ntatin has taught at APSU since 2007 and has been instrumental in revitalizing calculus courses. The chair of the mathematics section of the Middle Tennessee Academy of Mathematics, he has presented at several conferences, meetings and workshops. He earned a Ph.D. in mathematics from Ruhr-Universitaet Bochum in Bochum, Germany, a master’s in mathematics from the University of Ilorin in Ilorin, Nigeria, and a bacehlor’s in mathematics from the University of Jos in Jos, Nigeria.

The Provost Lecture Series seeks to foster a spirit of intellectual and scholarly inquiry among faculty, staff and students. The program will be used as a platform for APSU faculty members who are recent recipients of provost summer grants, who have been awarded faculty development leaves and who have engaged in recent scholarly inquiry during sabbatical leaves.

APSU faculty members with recent research of acclaim also will be given a platform within this series. In addition, other faculty members of local or widespread renown will be invited to lecture within this series.
