In recent years, many researchers have focused on several key areas in mathematics, particularly those involving number theory and algebraic geometry. These fields explore the relationships between numbers, shapes, and structures, which help in solving complex problems and building mathematical theories.
One prominent topic is the study of certain mathematical objects known as Motives. Motives can be considered as abstract shapes that can be studied similarly to geometric figures, but they have a unique role in number theory. This area has seen significant developments, especially in understanding their properties and how they interact with various mathematical constructs.
Motivation
The motivation behind exploring these subjects stems from their potential applications in different areas of mathematics and beyond. By studying motives, researchers aim to uncover deeper insights into the number systems and algebraic structures that govern various mathematical phenomena. This work can lead to advancements in related fields, including cryptography, coding theory, and even physics.
Selmer Groups
The Relevance ofSelmer groups are essential structures in number theory and algebraic geometry. They provide a way to study objects like elliptic curves and abelian varieties. The properties of Selmer groups can tell us a lot about the underlying motives they are associated with, such as how they relate to Galois representations and their respective invariants.
The study of Selmer groups can further enhance our understanding of how mathematical objects behave under various conditions. This knowledge is particularly important when examining the properties of motives that are non-ordinary or that exhibit specific types of reduction.
Non-Ordinary Motives
Non-ordinary motives represent one of the branches in a broader classification of motives. The term non-ordinary refers to motives that do not conform to the typical behavior expected from their counterparts. Such motives often arise in cases where unique mathematical properties are present, making them an intriguing area of study.
Research has highlighted various aspects of non-ordinary motives, including their signed Selmer groups. These groups serve as crucial tools for understanding the behavior of non-ordinary motives in relation to other mathematical entities.
Control Theorems
Control theorems are essential tools in the study of motives and their associated Selmer groups. These theorems provide conditions under which certain properties hold for Selmer groups. Understanding these conditions can lead to broader insights into the nature of the relationships between motives and their invariants.
By developing control theorems, researchers can establish connections between different types of motives and analyze how they behave under various conditions. This line of inquiry can ultimately lead to new results and advances in the broader field of number theory.
Congruences
The Role ofCongruences play a significant role in the study of Selmer groups and motives. They provide a means to compare different mathematical objects and examine their structure. Through the lens of congruences, researchers can explore how similar motives behave under specific conditions and what implications these similarities have for their properties.
By analyzing congruences in Selmer groups, one can establish important relationships that pave the way for understanding more profound theoretical implications. The ability to link different motives through congruences helps illuminate the intricate web of connections that exist within the field.
Iwasawa Algebra
Iwasawa algebra serves as another crucial element in the study of motives and the associated Selmer groups. This algebraic structure provides the necessary framework for analyzing the behavior of motives under various conditions. By employing Iwasawa algebra, researchers can delve deeper into the properties of Selmer groups and their relationship to number fields.
The connections between Iwasawa algebra, Selmer groups, and motives are at the heart of many contemporary studies. Understanding these relationships can lead to significant breakthroughs in our comprehension of number theory and its applications.
The Concept of Cotorsion
Cotorsion is a vital concept in the study of motives and Selmer groups. It refers to a specific type of behavior that certain algebraic structures exhibit. When a Selmer group is cotorsion, it means that the structure behaves well under various operations, making it easier to analyze and understand.
Developing a thorough understanding of cotorsion can lead to new insights and results within the broader fields of number theory and algebraic geometry. Researchers continually seek to characterize which Selmer groups exhibit cotorsion properties and under what conditions.
The Intersection of Various Disciplines
The study of motives, Selmer groups, and their properties often intersects with various other disciplines in mathematics. As researchers explore these connections, they uncover relationships that span across different mathematical fields. This interplay fosters collaboration and encourages the integration of ideas from diverse areas.
By bridging the gaps between different mathematical disciplines, researchers can craft new theories and methodologies that enhance our understanding of fundamental concepts. This collaborative spirit is vital for advancing mathematical knowledge.

Title: On the signed Selmer groups for motives at non-ordinary primes in $\mathbb{Z}_p^2$-extensions
Abstract: Generalizing the work of Kobayashi and the second author for elliptic curves with supersingular reduction at the prime $p$, B\"uy\"ukboduk and Lei constructed multi-signed Selmer groups over the cyclotomic $\mathbb{Z}_p$-extension of a number field $F$ for more general non-ordinary motives. In particular, their construction applies to abelian varieties over $F$ with good supersingular reduction at all the primes of $F$ above $p$. In this article, we scrutinize the case in which $F$ is imaginary quadratic, and prove a control theorem (that generalizes Kim's control theorem for elliptic curves) of multi-signed Selmer groups of non-ordinary motives over the maximal abelian pro-$p$ extension of $F$ that is unramified outside $p$, which is the $\mathbb{Z}_p^2$-extension of $F$. We apply it to derive a sufficient condition when these multi-signed Selmer groups are cotorsion over the corresponding two-variable Iwasawa algebra. Furthermore, we compare the Iwasawa $\mu$-invariants of multi-signed Selmer groups over the $\mathbb{Z}_p^2$-extension for two such representations which are congruent modulo $p$.
