Cubulating one-relator products with torsion
Benjamin Stucky
We generalize results of Lauer and Wise to show that a one-relator product of locally indicable groups whose defining relator has exponent at least 4 admits a proper and cocompact…

Asymptotic Confidence Regions for High-dimensional Structured Sparsity
Benjamin Stucky, Sara van de Geer
In the setting of high-dimensional linear regression models, we propose two frameworks for constructing pointwise and group confidence sets for penalized estimators which incorpora…

Sharp Oracle Inequalities for Square Root Regularization
Benjamin Stucky, Sara van de Geer
We study a set of regularization methods for high-dimensional linear regression models. These penalized estimators have the square root of the residual sum of squared errors as los…
