recommendations! Published in 2019 at "Mathematische Zeitschrift"

DOI: 10.1007/s00209-019-02416-4

Abstract: In this paper, we prove the sharp weighted bound for certain singular integrals which have non-smooth kernels and do not belong to the class of standard Calderón–Zygmund operators. Our assumptions are weaker than those known… read more here.

DOI: 10.1007/s11009-020-09809-7

Abstract: In this paper, we propose proximal splitting-type algorithms for sampling from distributions whose densities are not necessarily smooth nor log-concave. Our approach brings together tools from, on the one hand, variational analysis and non-smooth optimization,… read more here.

DOI: 10.1007/s11012-017-0641-1

Abstract: Models with impact or dry friction, yielding discontinuous velocities or accelerations, have motivated research for appropriate numerical methods in the community of non-smooth dynamics. In this work, we apply such methods on the grand piano… read more here.

DOI: 10.1007/s11044-019-09721-0

Abstract: Multibody models are often coupled with other domains in order to enlarge the scope of computer-based analysis. In particular, modeling multibody systems (MBSs) in interaction with granular media is of great interest for industrial process… read more here.

DOI: 10.1007/s11071-018-4189-y

Abstract: Saddle-node bifurcation can cause dynamical systems undergo large and sudden transitions in their response, which is very sensitive to stochastic and non-stationary influences that are unavoidable in practical applications. Therefore, it is essential to simultaneously… read more here.

DOI: 10.1007/s11071-020-05956-1

Abstract: In this paper, we consider some unusual features of dynamical regimes in the non-smooth potential $$V(x)=|x|$$ which is a piece-wise linear function. Also, we consider the dynamics in more complicated potential $$V(x)=\left| |x|-a\right| $$ which… read more here.

DOI: 10.1007/s11784-022-00934-z

Abstract: In this article we study the Arnold conjecture in settings where objects under consideration are no longer smooth but only continuous. The example of a Hamiltonian homeomorphism, on any closed sym-plectic manifold of dimension greater… read more here.

DOI: 10.1007/s13369-021-05961-5

Abstract: The non-smooth dynamic model can effectively handle unilateral constraints in multi-body systems, but its complex mathematical definition is difficult to be applied in engineering applications. To reduce the difficulty of this model’s application and to… read more here.

DOI: 10.1016/j.apm.2016.09.030

Abstract: The automotive industry is predominantly driven by legislations on stringent emissions. This has led to the introduction of downsized engines, incorporating turbocharging to maintain output power. As downsized engines have higher combustion pressures, the resulting… read more here.
