On local Galois deformation rings: generalised reductive groups

Vytautas PaÅ¡kÅ«nas, Julian Quast

We study deformation theory of mod $p$ Galois representations of $p$ -adic fields with values in generalised reductive group schemes, such as $L$ -groups and $C$ -groups. We show that…

Infinitesimal characters and Lafforgue's pseudocharacters

Vytautas PaÅ¡kÅ«nas, Julian Quast

We associate infinitesimal characters to $p$ -adic families of Lafforgue's pseudocharacters of the absolute Galois group of a $p$ -adic local field by extending a construction of Dos…

On local Galois deformation rings: generalised tori

Vytautas PaÅ¡kÅ«nas, Julian Quast

We study deformation theory of mod $p$ Galois representations of $p$ -adic fields with values in generalised tori, such as $L$ -groups of (possibly non-split) tori. We show that the…
