Absolutely partially hyperbolic surface endomorphisms are dynamically coherent
M. Andersson, W. Ranter
We show that if an endomorphism is absolutely partially hyperbolic, then it has a center foliation. Moreover, the center foliation is leaf conjuga…

Concentration bounds for intrinsic dimension estimation using Gaussian kernels
Martin Andersson
We prove finite-sample concentration and anti-concentration bounds for dimension estimation using Gaussian kernel sums. Our bounds provide explicit dependence on sample size, bandw…
