Which research fields deal with this variant definition of Boolean circuit depth?
Disclaimer: I admit that the question is not very clear. I think it cannot be helped because the question is very open-ended.
First of all, I present the interested type of circuits. We only consider ...

Finding subgraphs with high treewidth and constant degree
I am given a graph $G$ with treewidth $k$ and arbitrary degree, and I would like to find a subgraph $H$ of $G$ (not necessarily an induced subgraph) such that $H$ has constant degree and its treewidth ...

Bias of a random boolean low degree polynomial
What is the bias of a random Boolean function that can be represented as a low degree polynomial over the reals, i.e. has low Fourier degree?
More specifically, is it true that if we take a uniformly ...

Degree restriction for polynomials in $\mathsf{VP}$
why do we need the restriction on the degree for a polynomial to be in VP due to which $(\prod_{i=0}^{n} x_i)^{2^n}$ $\notin$ VP even though it has a poly-size circuit?

Random functions of low degree as a real polynomial
Is there a (reasonable) way to sample a uniformly random boolean function $f:\{0,1\}^n \to \{0,1\}$ whose degree as a real polynomial is at most $d$?
EDIT: Nisan and Szegedy have shown that a ...

hardness of approximating the chromatic number in graphs with bounded degree
I am looking for hardness results on vertex coloring of graphs with bounded degree.
Given a graph $G(V,E)$, we know that for any $\epsilon>0$, it's hard to approximate $\chi(G)$ within a factor ...

bounded outdegree bipartite spanners
Given an undirected graph $G = (V,E)$ and an integer $k > 0$, our objective is to find a subgraph $G' = (V ,E')$ where $E' \subseteq E$ such that $G'$ has the three following properties :
$G'$ ...

Is feedback vertex set problem is solvable in polynomial time for 3-degree bounded graphs?
Feedback Vertex Set is NP-complete for general graphs. It is known to be NP-complete for degree-8 bounded graphs due to a reduction from vertex cover.
The Wikipedia article says that it is poly-time ...
