Smooth Anosov Katok Diffeomorphisms With Generic Measure
Divya Khurana
We construct a plethora of Anosov-Katok diffeomorphisms with non-ergodic generic measures and various other mixing and topological properties. We also construct an explicit collect…
Local approximate symmetry of Birkhoff-James orthogonality in normed linear spaces
Jacek Chmieliński, Divya Khurana, Debmalya Sain
Two different notions of approximate Birkhoff-James orthogonality in nor\-med linear spaces have been introduced by Dragomir and Chmie\-liń\-ski. In the present paper we consider a…
Norm derivatives and geometry of bilinear operators
Divya Khurana, Debmalya Sain
We study the norm derivatives in the context of Birkhoff-James orthogonality in real Banach spaces. As an application of this, we obtain a complete characterization of the left-sym…
Weight-partially greedy bases and weight-Property
Divya Khurana
In this paper, motivated by the notion of -Property defined in [2], we introduce the notions of -left Property and -right Property . We also introduce the…
Characterizations of almost greedy and partially greedy bases
S. J. Dilworth, Divya Khurana
We shall present new characterizations of partially greedy and almost greedy bases. A new class of basis (which we call reverse partially greedy basis) arises naturally from these…
