Surface Bundles in Topology, Algebraic Geometry, and Group Theory
, 2020 Surface Bundles A surface is one of the most basic objects in topology, but themathematics of surfaces spills out far beyond its source, penetrating deeply into fields as diverse as algebraic geometry, complex analysis, dynamics, hyperbolic geometry ...

IET Renewable Power Generation, EarlyView., 2022 This research work explains a sliding mode controller‐based multilevel inverter for grid integrated photovoltaic (PV) power structure. A gravitational search algorithm (GSA) based on maximum power point tracking (MPPT) has also been discussed for optimal PV power achievement.

Topological Expansion, Study and Applications [PDF]
Topology and its Applications, 160, p 2121-2139 , (2013), 2012 In this paper, we introduce the notion of expanding topological space. We define the topological expansion of a topological space via local multi-homeomorphism over coproduct topology, and we prove that the coproduct family associated to any fractal family of topological spaces is expanding.

Space, matter and topology [PDF]
Nature Physics 12, 616 (2016), 2016 An old branch of mathematics, Topology, has opened the road to the discovery of new phases of matter. A hidden topology in the energy spectrum is the key for novel conducting/insulating properties of topological matter.

The Gromov width of complex Grassmannians [PDF]
, 2005 We show that the Gromov width of the Grassmannian of complex k-planes in C^n is equal to one when the symplectic form is normalized so that it generates the integral cohomology in degree 2. We deduce the lower bound from more general results. For example,

Brandt extensions and primitive topological inverse semigroups [PDF]
Published in: International Journal of Mathematics and
Mathematical Sciences 2010 (2010) Article ID 671401, 13 pages, 2010 In the paper we study (countably) compact and (absolutely) $H$-closed primitive topological inverse semigroups. We describe the structure of compact and countably compact primitive topological inverse semigroups and show that any countably compact primitive topological inverse semigroup embeds into a compact primitive topological inverse semigroup.

Dyer-Lashof-Cohen operations in Hochschild cohomology [PDF]
, 2005 We give explicit formulae for operations in Hochschild cohomology which are analogous to the operations in the homology of double loop spaces. As a corollary we obtain that any brace algebra in finite characteristic is always a restricted Lie algebra ...
