New $AdS_3$ Branes and Boundary States [PDF]
, 2001 We examine D-branes on $AdS_3$, and find a three-brane wrapping the entire $AdS_3$, in addition to 1-branes and instantonic 2-branes previously discussed in the literature.

Topological conjugacies of piecewise monotone interval maps
International Journal of Mathematics and Mathematical Sciences, 2001 Our aim is to establish the topological conjugacy between piecewise monotone expansive interval maps and piecewise linear maps. First, we are concerned with maps satisfying a Markov condition and next with those admitting a certain countable partition ...

D-branes in the WZW model [PDF]
, 1999 It is stated in the literature that D-branes in the WZW-model associated with the gluing condition J = - \bar{J} along the boundary correspond to branes filling out the whole group volume.

Prequantization of the Moduli Space of Flat ${\rm PU}(p)$-Bundles with Prescribed Boundary Holonomies [PDF]
, 2014 Using the framework of quasi-Hamiltonian actions, we compute the obstruction to prequantization for the moduli space of flat ${\rm PU}(p)$-bundles over a compact orientable surface with prescribed holonomies around boundary components, where $p>2$ is ...

Quadratic Function Chaotic System and its Application on Digital Image Encryption
IEEE Access, 2020 To obtain chaotic systems with good properties to help chaos based image encryption, this paper first study the condition under which quadratic functions can be used as pseudo-random sequence generator.

Density of hyperbolicity for classes of real transcendental entire functions and circle maps [PDF]
, 2014 We prove density of hyperbolicity in spaces of (i) real transcendental entire functions, bounded on the real line, whose singular set is finite and real and (ii) transcendental self-maps of the punctured plane which preserve the circle and whose singular

Conjugacy of Self-Adjoint Difference Equations of Even Order
Abstract and Applied Analysis, 2011 We study oscillation properties of 2n-order Sturm-Liouville difference equations. For these equations, we show a conjugacy criterion using the p-criticality (the existence of linear dependent recessive solutions at ∞ and -∞).

Twisted conjugacy in soluble arithmetic groups [PDF]
Mathematische Nachrichten, 2020 Reidemeister numbers of group automorphisms encode the number of twisted conjugacy classes of groups and might yield information about self‐maps of spaces related to the given objects.
