We demonstrate that various cla ssical examples of operator algebras - such as group(oid) algebras - have a nonarchimedean counterpart. The category of p-adic operator algebras exh ibits a similar flavor to the category of real and complex $C^*$-algebras\ , featuring limits\, colimits\, tensor products\, crossed products and an enveloping construction permitting us to construct p-adic operator algebra s from involutive algebras over $Z_p$. Finally\, we briefly discuss an ana logue of topological K-theory for Banach $Z_p$-algebras\, and compute it i n basic examples\, like Cuntz algebras and rotation algebras.\n\nThis is j oint work with Luiz Felipe Garcia and Devarshi Mukherjee.\n LOCATION:https://researchseminars.org/talk/NYC-NCG/165/ END:VEVENT END:VCALENDAR
