Recognized for Excellence in Dynamical Systems Research
Vaughn Climenhaga, assistant professor in the Department of Mathematics, is described as a 鈥榖right young star,鈥 one of the 鈥榳orld鈥檚 leading researchers in the field of non-uniformly hyperbolic dynamical systems.鈥
Vaughn Climenhaga, assistant professor of mathematics, studies non-uniform hyperbolicity.In recognition of these accomplishments, Climenhaga has been awarded the College of
Natural Sciences and Mathematics鈥 Junior Faculty Award for Excellence in Research.
This award, which was introduced in 2015, is given every year to a faculty member
at the assistant professor level in recognition of their exceptional research contributions.
Selection for this award requires nomination, with only one allowed per department. In support of this nomination, three respected researchers, who work within the field but are unaffiliated with UH, are asked to write letters of recommendation, along with the head of the department.
For this honor, Climenhaga will be presented with a plaque and an award of $5,000.
Climenhaga鈥檚 research, for which he was awarded an NSF CAREER Award, is focused on understanding dynamical systems that exhibit non-uniform hyperbolicity.
鈥淗yperbolicity is the phenomenon of small changes in starting conditions getting blown up very quickly, leading to significantly different outcomes and unpredictable results,鈥 said Climenhaga, who joined UH as an assistant professor in 2012.
In popular culture, hyperbolicity is described as 鈥渃haos theory鈥 and 鈥渢he butterfly effect,鈥 with the hypothetical question: 鈥楧oes the flap of a butterfly鈥檚 wings in Brazil set off a tornado in Texas?鈥
With non-uniform hyperbolicity, there will be periods of predictability, and then sudden moments where the different states of the system separate very quickly, going from predictable to random,鈥 Climenhaga said.
An example of non-uniform hyperbolicity would be throwing a pair of dice. When these dice are flying through the air, they behave in a way that is predictable and not too sensitive to small changes in the initial conditions. When these dice land, there will be a moment of time when a very tiny change, such as the angle at which they land, will have a significant impact on the final outcome, generating randomness.
Climenhaga鈥檚 research focuses on adapting mathematical techniques used to describe uniformly hyperbolic systems for use in non-uniformly hyperbolic systems.
As one recommender wrote of Climenhaga鈥檚 research, his 鈥渨ork has tremendous potential: the conditions are natural, canonical, and seem to be well-adapted to general theoretical treatment.鈥 Another recommender noted that 鈥渉e has already made several very significant contributions鈥 and is 鈥渙n a clear path for producing even more spectacular achievements in the future.鈥
