Bökstedt periodicity and quotients of DVRs [PDF]

Compositio Mathematica, 2022
In this paper we compute the topological Hochschild homology of quotients of discrete valuation rings (DVRs). Along the way we give a short argument for Bökstedt periodicity and generalizations over various other bases. Our strategy also gives a very efficient way to redo the computations of $\operatorname {THH}$ (respectively, logarithmic ...

Power Quality Improvement by using DVR

Journal of Electrical Engineering and Electronics Design, 2023
A power system having three main subsystems such as generation, transmission and distribution. While transmitting the power from generation to end user’s utility has to face power quality issues such as voltage sag, voltage swell, harmonics, transmission losses, transients, voltage fluctuation/ flickering and many more, there are various devices and ...
