  1. Abstract Let $$n$$ be either  $$2$$ or an odd integer greater than  $$1$$ , and fix a prime  $p>2(n+1)$ . Under standard ‘adequate image’ assumptions, we show that the set of components of $$n$$ -dimensional $$p$$ -adic potentially semistable local Galois deformation rings that are seen by potentially automorphic compatible systems of polarizable Galois representations over some CM field is independent of the particular global situation. We also (under the same assumption on  $$n$$ ) improve on the main potential automorphy result of Barnet-Lamb et al.  [Potential automorphy and change of weight, Ann. of Math. (2)   179 (2) (2014), 501–609], replacing ‘potentially diagonalizable’ by ‘potentially globally realizable’.

  2. We construct, over any CM field, compatible systems of $$l$$ -adic Galois representations that appear in the cohomology of algebraic varieties and have (for all $$l$$ ) algebraic monodromy groups equal to the exceptional group of type $$E_{6}$$ .

  3. We prove the explicit version of the Buzzard–Diamond–Jarvis conjecture formulated by Dembele et al. ( Serre weights and wild ramification in two-dimensional Galois representations , Preprint (2016), arXiv:1603.07708 [math.NT]). More precisely, we prove that it is equivalent to the original Buzzard–Diamond–Jarvis conjecture, which was proved for odd primes (under a mild Taylor–Wiles hypothesis) in earlier work of the third author and coauthors.
