چکیده
For posets P and Q, extremal saturation problems about weak strong P-free subposets of Q have been studied mostly in the case is Boolean poset Qn, all subsets an n-element set ordered by inclusion. In this paper, we study some instances problem with being grid, its connections to forbidden submatrix problem.

Supersaturation and stability for forbidden subposet problems
We address a supersaturation problem in the context of forbidden subposets. A family F of sets is said to contain the poset P if there is an injection i : P → F such that p ≤P q implies i(p) ⊂ i(q). The poset on four elements a, b, c, d with a, b ≤ c, d is called a butterfly. The maximum size of a family F ⊆ 2 that does not contain a butterfly is ( n bn/2c ) + ( n bn/2c+1 ) as proved by De Boni...
متن کاملInduced and Non-induced Forbidden Subposet Problems
The problem of determining the maximum size La(n, P ) that a P -free subposet of the Boolean lattice Bn can have, attracted the attention of many researchers, but little is known about the induced version of these problems. In this paper we determine the asymptotic behavior of La∗(n, P ), the maximum size that an induced P -free subposet of the Boolean lattice Bn can have for the case when P is...
متن کاملSet Families with a Forbidden Subposet
We asymptotically determine the size of the largest family F of subsets of {1, . . . , n} not containing a given poset P if the Hasse diagram of P is a tree. This is a qualitative generalization of several known results including Sperner’s theorem. Introduction We say that a poset P is a subposet of a poset P ′ if there is an injective map f : P → P ′ such that a 6P b implies f(a) 6P ′ f(b). A ...
متن کاملExact Forbidden Subposet Results using Chain Decompositions of the Cycle
We introduce a method of decomposing the family of intervals along a cyclic permutation into chains to determine the size of the largest family of subsets of [n] not containing one or more given posets as a subposet. De Bonis, Katona and Swanepoel determined the size of the largest butterfly-free family. We strengthen this result by showing that, for certain posets containing the butterfly pose...
متن کاملOn Families of Subsets With a Forbidden Subposet
Let F ⊂ 2[n] be a family of subsets of {1, 2, . . . , n}. For any poset H, we say F is H-free if F does not contain any subposet isomorphic to H. Katona and others have investigated the behavior of La(n,H), which denotes the maximum size of H-free families F ⊂ 2[n]. Here we use a new approach, which is to apply methods from extremal graph theory and probability theory to identify new classes of...
