The multinomial coefﬁcient n+1 k;k+1;n 2k counts paths with k down steps, k +1 up steps, and n 2k ﬂat steps. Since these paths end at height 1, we can apply the theorem to get that for i from 1 to n +1, the number of these paths with i nonpositive points is 1 n+1 n+ k;k+1;n 2k NettetCatalan-like numbers. In this section, we ﬁrst demonstrate that the generalized Motzkin numbers M n(b,c) is precisely the Catalan-like numbers corresponding to the generalized Motzkin triangle M(b,c), i.e., M n(b,c) = M n,0(b,c), and then apply this result to prove Theorem 1. The generalized Motzkin triangle is also a Riordan array. clerkenwell police court

NettetThe Sylvester–Gallai theorem in geometry states that every finite set of points in the Euclidean plane has a line that passes through exactly two of the points or a line that passes through all of them.

The generalization lies in the fact that we formulate the Farkas lemma in the setting of two vector spaces over a common linearly ordered field where one of the vector spaces is also linearly ordered.

NettetFourier–Motzkin elimination, also known as the FME method, is a mathematical algorithm for eliminating variables from a system of linear inequalities. It can output real solutions. The algorithm is named after Joseph Fourier [1] who proposed the method in 1826 and Theodore Motzkin who re-discovered it in 1936.

NettetMotzkin’s transposition theorem (MTT) [1] is a so-called theorem of the alternative. It deals with the question whether or not a given sys-tem of linear inequalities has a solution. NettetWe provide the proofs of Theorems 2.1 and 2.5 in Sections 4 and 5, respectively. We also prove Theorems 2.2-2.3 and state four conjectures (cf. Conjectures 5.1-5.3 and 5.5) related to Motzkin numbers in Section 5, including lower bounds on the order of di erences for all primes. 2. Main results
