HARD LEFSCHETZ ACTIONS IN RIEMANNIAN GEOMETRY WITH SPECIAL HOLONOMY [PDF]
, 2008 It is known that the hard Lefschetz action, together with K\"ahler identities for K\"ahler (resp. hyperk\"ahler) manifolds, determines a $\mathfrak{su}(1,1)_{sup}$ (resp. $\mathfrak{sp}(1,1)_{sup}$) Lie superalgebra action on differential forms.

External Fields as Intrinsic Geometry [PDF]
, 2000 There is an interesting dichotomy between a space-time metric considered as external field in a flat background and the same considered as an intrinsic part of the geometry of space-time.

Tableaux over Lie algebras, integrable systems, and classical surface theory [PDF]
, 2006 Starting from suitable tableaux over finite dimensional Lie algebras, we provide a scheme for producing involutive linear Pfaffian systems related to various classes of submanifolds in homogeneous spaces which constitute integrable systems. These include

Secondary theories for simplicial manifolds and classifying spaces
, 2007 We define secondary theories and characteristic classes for simplicial smooth manifolds generalizing Karoubi's multiplicative K-theory and multiplicative cohomology groups for smooth manifolds.

Geodetikus loopok Lie elmélete = Lie theory geodesic loops [PDF]
, 2007 A geodetikus loopok alapvető modellként szolgálnak a differenciálható loopok elméletében. Vizsgáljuk a geodetikusokkal kapcsolatos differenciálgeometriai struktúrákat, a tanulmányozott módszereket pedig alkalmaztuk a differenciálható loopok elméletében ...

Molecular determinants of signal transduction in tropomyosin receptor kinases
FEBS Open Bio, EarlyView.Tropomyosin receptor kinases control critical neuronal functions, but how do the same receptors produce diverse cellular responses? This review explores the structural mechanisms behind Trk signaling diversity, focusing on allosteric modulation and ligand bias.

A Meeting of Great Minds, Sophus Lie and John Nash throughout their Works
, 2015 That is to say, Lie has been in Astronomy and Nash in Chemical Engineering. Whereas, when they worked on mathematics, the first had Lobatchevski award in 1897 and the second, Nobel prize 1994 and Abel award 2015 (Niels Abel is the uncle of the wife of ...

Heisenberg double versus deformed derivatives [PDF]
, 2009 A common replacement of the tangent space to a noncommutative space whose coordinate algebra is the enveloping algebra of a Lie algebra is generated by the deformed derivatives, usually defined by procedures involving orderings among noncommutative ...

Advanced Engineering Materials, EarlyView.The role of various alloying elements in face‐centered cubic aluminum on the barrier of a Shockley partial dislocation during its motion is presented. The study aims to understand how alloying atoms such as Mg, Si, and Zr affect the energy landscape for dislocation motion, thus influencing the solid solution hardening and softening in aluminum, which ...
