Hi,
In my problem, my optimization variable lies in a Stiefel Manifold `A (3x2)`. My original problem `P1` is:
```
max z
s.t. g(A) >= z
f(A) >= Q
A lies in Stiefel Manifold (3x2…

Although the example tutorials include use of JAX in Pymanopt optimization, I haven't seen explicit use of JAX jit compilation functionality. Is compilation happening in the background? If not, is it …

https://www.pymanopt.org/ provides numerical optimization algorithms over various families of manifolds (`Sphere`, `Stiefel`, `Grassmann`, ...) and their products.
I propose to

Hello,
In my problem, the variable is a complex vector **w** and its norm ||**w**||=5, so I think it is a complex sphere manifold. But how could I define this complex sphere manifold? I only find t…

Hi all, I've been working with constraints of orthogonality of the columns of a matrix, but not orthonormality. This is, instead of the Stiefel manifold, this is the manifold of matrices where XX^T is…

Recent progress applying MARVEL in LM showed better performance compared to LoRA.
I didn't read the paper thoroughly but this paper also seems to be app…

Manifolds and Optim walk into a bar asking for `Spheres`. Manifolds says the `norm` is to `project!`

It is often useful to define linear operators on arbitrary linear spaces, not necessarily AbstractVectors (e.g. the discretization of a n-d PDE). At the moment this is not supported by LinearMaps.

Hi,
I just checked back, it seems there has been lots of activity on this project, great! Is it ready for prime time? In particular, can we replace Optim's implementation of manifolds with this pac…
