Potentially semi stable galois representations?

Let E, K be a finite extensions of Q_p and V a finite dimensional E vector space which is also a potentially semistable G_K module (that is, V is semistable over a finite extension of K). Let K'...

Theta Functions as sections of determinant bundles?

Let X be a smooth curve over k, S a noetherian scheme over k, F a vector bundle on X\times_k S, L a line bundle X\times_k S which is the pullback of a line bundle on X. The theta function...

Why is the functor M_{G,X} of families of G bundles on a connected projective curve X not representable?

Let G be a reductive group over k, X a connected projective curve over k. Associate to a scheme S over a field k the set M_{G,X}(S) of isomorphism classes of G bundles on S\times X, this defines a...

How do I find the primes at which an l adic representation associated to a variety is rammified?

We consider the l adic representation of a number field K constructed from an elliptic curve E over K with given rational point 0. So this is basically the natural representation R:Gal(Q^{alg}/K)...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
