Published in 2019 at "Journal of Mathematical Sciences"

DOI: 10.1007/s10958-019-04256-3

Abstract: We study linear images of a symmetric convex body C ⊆ ℝN under an n × N Gaussian random matrix G, where N ≥ n. Special cases include common models of Gaussian random polytopes and… read more here.

Published in 2023 at "Wuhan University Journal of Natural Sciences"

DOI: 10.1051/wujns/2023282093

Abstract: In this paper, we establish a characterization of the polarity mapping for 1-dimensional convex bodies, which is a supplement to the result for such a characterization obtained by Böröczky and Schneider. read more here.

Published in 2019 at "Journal of Inequalities and Applications"

DOI: 10.1186/s13660-019-2085-8

Abstract: AbstractWe consider the following inequality: μ(L)n−kn≤CkmaxH∈Grn−kμ(L∩H), $$\begin{aligned} \mu (L)^{\frac{n-k}{n}} \leq C^{k}\max_{H\in \mathit{Gr}_{n-k}}\mu (L \cap H), \end{aligned}$$ which is a variant of the notable slicing inequality in convex geometry, where L is an origin-symmetric star body… read more here.

Published in 2023 at "Mathematics"

DOI: 10.3390/math11092000

Abstract: Estimating covering functionals of convex bodies is an important part of Chuanming Zong’s program to attack Hadwiger’s covering conjecture, which is a long-standing open problem from convex and discrete geometry. In this paper, we transform… read more here.
