Diddordebau ymchwil

Mae David E Evans wedi cyhoeddi gyda Yasuyuki Kawahigashi, monograff Symmetries Cwantwm ar Algebras Gweithredwr - agweddau cyfuniadol a chorfforol algebras gweithredwyr (Gweler yma am y rhestr o ddiweddariadau / cywiriadau). Mae hyn yn barhad o waith Evans yn ei gydweithrediadau blaenorol gydag Araki a Lewis ar ddull C *-algebra o drawsnewid cyfnod yn y model Ising dau ddimensiwn. Mae gan Evans ddiddordebau hefyd yn yr astudiaeth o amenable C*-algebras gan K- anifeiliad theoretig neu topolegol, e.e. mynegiant meidraidd yn galluogi C syml *- algebras fel terfyn anwythol blociau adeiladu symlach - mynegodd Elliott ac Evans yr algebra cylchdro afresymol fel terfynau anwythol o algebrai cylch. Ceir llawer o gyfnewid syniadau o isffactorau anghydnaws ac amenable C*-algebras yn y gwaith hwn (e.e. trwy syniadau cyffredin o nodweddion orbifolds a Rokhlin o awtomorffeddau). Mae gwaith diweddar wedi canolbwyntio ar astudio swyddogaethau rhaniad invariant modiwlaidd trwy isffactorau a chydbwysedd twisted K-theory – yr olaf yw rhaglen ymchwil gyda Terry Gannon.
