The Big-line-big-clique conjecture is a concept in the field of combinatorics, more specifically in graph theory. It conjectures properties related to the structure and size of certain types of graphs, particularly concerning the relationships between cliques and line graphs. A clique in a graph is a subset of vertices such that every two distinct vertices in the subset are adjacent.

Borsuk's conjecture, proposed by Polish mathematician Karol Borsuk in 1933, asserts that any bounded, convex subset of Euclidean space \( \mathbb{R}^n \) can be partitioned into \( n + 1 \) or fewer subsets, each of which has a smaller diameter than the original set.

The Dissection Problem refers to a type of mathematical problem in geometry and combinatorial optimization where the goal is to dissect or cut a shape into a finite number of pieces that can be reassembled into another shape. This kind of problem often involves exploring how different shapes can be transformed into one another through geometric means.

Equidissection is a mathematical concept related to the idea of dividing shapes into pieces in such a way that the pieces can be rearranged to form another shape of equal area or volume. It involves partitioning a geometric figure into smaller pieces that can be reconfigured without changing their size, typically to demonstrate equivalence in area or volume between different figures. One of the popular contexts for discussing equidissection is in geometry, specifically in polygonal and polyhedral dissections.

The Hadwiger Conjecture is a significant statement in combinatorial geometry that relates to the coloring of the plane with respect to convex sets, particularly focusing on the properties of regions defined by convex shapes.

The "kissing number" refers to the maximum number of non-overlapping spheres that can simultaneously touch another sphere of the same size in a given dimensional space. The concept can be applied in multiple dimensions, and the kissing number varies depending on the dimension. Here are some known kissing numbers: 1. **In 1 dimension**: The kissing number is **2**. A line segment (sphere in 1D) can touch two other line segments at its endpoints.

Lebesgue's universal covering problem is a question in the field of topology, particularly concerning the properties of spaces that can be covered by certain kinds of collections of sets. Specifically, the problem asks whether every bounded measurable set in a Euclidean space can be covered by a countable union of sets of arbitrarily small Lebesgue measure.

The "Mountain Climbing Problem" typically refers to a type of optimization problem or search problem that can often be framed in the context of artificial intelligence, algorithms, or problem-solving techniques.

The orchard-planting problem is a problem in optimization typically found in operations research and mathematical programming. It involves the strategic placement of trees or plants in an orchard to maximize certain objectives while adhering to constraints. The problem can vary in its specifics, but it often includes considerations like: 1. **Maximizing Yield**: The primary goal is often to maximize the yield of fruits or nuts from the planted trees. This can depend on factors like tree density, spacing, and compatibility between different species.
