The phrase "kernel of a problem" is correct and usable in written English.
It usually refers to the essential or core issue or challenge at hand, and is often used in the context of problem solving. For example, "Once I was able to identify the kernel of the problem, I was able to create a plan of action to address it."
The kernel for 12Society came out of a problem that the co-founders identified while at JungleCents, specifically that many brands out there want not only to get the attention of the 18 to 35-year-old male demographic, but they want to get them actively engaging — and shopping.

A further, this time smaller, alternative layer that contains only the kernel of the scientific problem (as perceived by the present author, which may or may not correspond to the perception of the original [25] authors) has been added here, and again four key measurement annotations made, together with selected bonds highlighted in a different colour.
Let 0 ≤ β ≤ α and let P ( x, y ) = 1 ω n 1 − | x | 2 | x − y | n be the Poisson kernel of the Dirichlet problem, and ω n the area of the unit sphere.
A kernel of a fascinating play is here.
Provided the kernel is positive definite it constitutes the reproducing kernel of a unique reproducing kernel Hilbert space (RKHS) [ 53].
The best choice of kernel for a given problem is still a research problem [ 7].
