Chess grandmaster Garry Kasparov was arrested, in absentia, by Russia for creating and leading a "terrorist" group. This group, the Renew Democracy Initiative, tweeted that this "means he's been especially effective in fighting for freedom"
His own statement was great as well:

Index theory for H-elliptic and transversally H-elliptic operators from $KK$-theoretic viewpoint
This research comprehensively describes the transversally H-elliptic operators and investigates the index theorem of H-elliptic and transversally H-elliptic operators from the perspective of $KK$-theory, applying Kasparov's methodology. Moreover, the analysis methodically examines specific conditions, with a focus on the Fourier transform of the nilpotent group $C^{\ast}$-algebra. The findings demonstrate enhanced methods for analyzing the hypoellipticity of operators, presenting a robust frame…

Index theory for H-elliptic and transversally H-elliptic operators from KK theoretic viewpoint
This study provides a comprehensive definition for transversally H-elliptic operators and explores the index theorem of H-elliptic and transversally H-elliptic operators through the lens of KK-theory, employing Kasparov's approach. Furthermore, our analysis incorporates a detailed examination of conditions, specifically delving into the Fourier transform of the nilpotent group C^{\ast}-algebra.

Generalized homomorphisms and KK with extra structure
We develop the approach via quasihomomorphisms and the universal algebra $qA$ to Kasparov's $KK$-theory, so as to cover versions of $KK$ such as $KK^{nuc}$, $KK^G$ and ideal related $KK$-theory.
