The scalar curvature problem on four-dimensional manifolds
Communications on Pure and Applied Analysis, 2020 We study the problem of existence of conformal metrics with prescribed scalar curvatures on a closed Riemannian \begin{document}$ 4 $\end{document} -manifold not conformally diffeomorphic to the standard sphere \begin{document}$ S^{4} $\end{document ...

The Ups and Downs of Cyclic Universes [PDF]
, 2007 We investigate homogeneous and isotropic oscillating cosmologies with multiple fluid components. Transfer of energy between these fluids is included in order to model the effects of non-equilibrium behavior on closed universes.

Total mean curvature, scalar curvature, and a variational analog of Brown-York mass
, 2016 We study the supremum of the total mean curvature on the boundary of compact, mean-convex 3-manifolds with nonnegative scalar curvature, and a prescribed boundary metric.

Prescribing Scalar Curvature on S3, S4 and Related Problems
Journal of Functional Analysis, 1993 AbstractWe show that for the prescribing scalar curvature problem on Sn (n = 3, 4), we can perturb (in an explicit way) any given positive continuous function in any neighborhood of any given point on Sn such that for the perturbed function there exist many solutions.

Yamabe flow with prescribed scalar curvature [PDF]
Pacific Journal of Mathematics, 2017 In this work, we study the Yamabe flow corresponding to the prescribed scalar curvature problem on compact Riemannian manifolds with negative scalar curvature. The long time existence and convergence of the flow are proved under appropriate conditions on

Advanced Biology, EarlyView.The unrolling of the peltate leaves in Syngonium podophyllum is analyzed and quantified (left‐hand side to center). These measurements serve to verify a mathematical model for leaf unrolling based on the model used in Schmidt (2007). An additional formula for obtaining a layer mismatch from a prescribed radius is derived.
