SUMMARY:CCMS Colloquium: Puttipong Pongtanapaisan (Pitzer)
DESCRIPTION:CCMS Colloquium invites you to a talk by Puttipong Pongtanapaisan (Pitzer)\n\n \nTitle:  Derivatives and the Shape of Graphs\n \nAbstract:  Reading the title of this talk\, perhaps you think you are going to hear about Calculus I. I stole the title from a section of Stewart’s popular calculus book. But actually\, I am going to talk about geometry and topology\, and the root idea already appears in Calculus I. In real life\, shapes such as proteins and DNA can be tangled up in space. These can be modeled as graphs embedded in three-dimensional space\, and some applied mathematicians also call these networks. In calculus\, you learn that information about derivatives\, such as the number of local maxima and where they appear\, tells us a great deal about the graph itself. I am going to apply this same philosophy to knotted graphs in three-dimensional space and demonstrate that one protein is more complexly entangled than another.\n \nBio: Puttipong Pongtanapaisan obtained his Ph.D. at the University of Iowa\, where he studied low-dimensional topology under the supervision of Dr. Maggy Tomova. His previous positions include a PIMS Postdoctoral Fellow at the University of Saskatchewan and a Postdoctoral Associate at Arizona State University. His research explores knotted shapes in confinement by analyzing the arrangement of local maxima and minima.

SUMMARY:CCMS Colloquium: Ryan Moruzzi (CSU Northridge)
DESCRIPTION:CCMS Colloquium invites you to a talk by Ryan Moruzzi (CSU Northridge)\n\n \nTitle:  Exploring Leaky Forcing Through Hopi Rectangle graphs\n \nAbstract:  Leaky forcing\, introduced in 2019\, is a graph-coloring process motivated by questions of network monitoring\, in which the loss of information can hinder propagation through a graph. As a variant of standard zero forcing\, leaky forcing has opened new directions in the study of zero forcing and related graph parameters. In this talk\, based on joint work with students\, we will collaboratively investigate the leaky forcing number for several graphs before focusing on a family of graphs called Hopi Rectangles. By viewing these graphs as induced subgraphs of d-dimensional grid graphs\, we classify their leaky forcing numbers. Time permitting\, we will conclude by discussing the maximum nullity of this graph family and its connection to standard zero forcing.\n \nBio: I am a husband\, father\, sports enthusiast\, and mathematician who enjoys spending time with my family and the energy of sports. I earned my B.S. in Mathematics from Cal Poly Pomona and my Ph.D. in Mathematics from the University of California\, Riverside\, where I specialized in representation theory. My research interests lie in combinatorics\, discrete mathematics\, and linear algebra\, with particular emphasis on the inverse eigenvalue problem of a graph\, zero forcing and its variations\, throttling\, and propagation time on graphs. I also care deeply about teaching and mentorship\, and as an educator I am committed to fostering equity and inclusion by working intentionally to remove barriers that limit student success.

SUMMARY:CCMS Colloquium: Manuel Reyes (UCI)
DESCRIPTION:CCMS Colloquium invites you to a talk by Manuel Reyes (UCI)\n\n \nTitle: When XY is not equal to YX\n \nAbstract:  The commutative property of algebra states that the order of multiplication makes no difference: XY = YX. This property is so ingrained in our experience that it becomes difficult to imagine how algebra would function without it! If the commutative property fails\, we step into the territory of noncommutative algebra. Where and why does noncommutative algebra occur? How different is it from our ordinary commutative algebra? This talk will be an introduction to noncommutative algebra\, with several examples and a glimpse into current research problems.\n \nBio: Manny Reyes is an Associate Professor of Mathematics at UC Irvine. His research lies at the intersection of several topics including ring theory\, noncommutative geometry\, category theory\, and quantum foundations. After studying at Westmont College and UC Berkeley\, he was a postdoctoral fellow at UC San Diego and a faculty member for several years at Bowdoin College before returning to California. He strives to teach in a way that invites anyone to discover a passion for mathematics\, regardless of their past experiences. \n
