Pancreatic cancer often shows no clear symptoms until it has already spread, making it one of the deadliest common cancers. An affordable early screening method could dramatically improve survival rates.

Talks over agricultural subsidies and intellectual property rights have dragged on for over twenty years without resolution in some cases, because neither side is willing to compromise. This gridlock pushes countries toward smaller side deals that fragment the global trading system further.

Some mathematical series behave predictably, while others sit in ambiguous territory where convergence is difficult to prove definitively. Fully resolving these cases remains an active area of mathematical research.

Thousands of victims from past wars and disasters remain unidentified, leaving families without closure decades later. Better, cheaper identification methods could resolve many of these long-standing cases.

Early detection dramatically improves skin cancer survival rates, but many people lack easy access to dermatology screening. A cheap, widely available detection tool could catch far more cases before they become dangerous.

Many Diophantine equations, which ask for whole-number solutions, resist any general method for predicting how many solutions exist. Solving specific cases has taken decades and earned major mathematical prizes.

The famous four-color theorem was resolved for flat maps, but generalizing the problem to more complex or higher-dimensional surfaces remains unsettled in several cases. This continues to be explored in graph theory and topology.

Finding the shortest possible route through many locations becomes exponentially harder as the number of locations grows, and no efficient exact solution is known for all cases. This unresolved question sits at the heart of computational optimization theory.

Partition numbers grow in a complex, only partially understood way, and while excellent approximations exist, a complete exact predictive formula for all cases remains elusive. This continues to be an active area within combinatorics and number theory.

Ramsey-type problems ask whether order must always emerge within sufficiently large or complex systems, and while some cases are proven, the general boundaries remain incompletely mapped. This connects deeply to combinatorics and the philosophy of mathematical order.

Dissection problems, which ask how shapes can be cut and rearranged, often lack complete general solutions beyond specific well-studied cases. This remains an open and often surprisingly difficult area of combinatorial geometry.

Self-referential systems often run into paradoxes, and while specific fixes exist for particular cases, no fully general and complete solution has been proven for every possible self-describing system. This unresolved tension remains central to mathematical logic and computer science.

Additive combinatorics explores these kinds of guaranteed substructure questions extensively, but many specific cases remain without a fully general proof. This continues to be an active and evolving research area.

History has shown some conjectures hold for enormous ranges before finally failing, raising the unresolved question of how confidently mathematicians can ever trust patterns observed only in finite testing. This shapes ongoing debates about the reliability of computational evidence in mathematics.

Specific techniques exist for counting solutions in many cases, but a complete and general method covering every possible polynomial system remains an unresolved goal in algebraic geometry. This continues to be an active area of mathematical research.

Symmetry groups have been classified extensively for finite cases, but infinite symmetry structures present ongoing classification challenges that remain incompletely resolved. This shapes foundational research in both algebra and geometry.

Logical simplification techniques work well for many cases, but a fully general method guaranteed to simplify every possible logical structure remains unresolved. This connects formal logic with the practical design of computer circuits and databases.

Scheduling problems appear throughout logistics and computing, and while efficient solutions exist for many specific cases, a fully general efficient method remains unresolved for the broader problem family. This unresolved question connects theoretical computer science with real-world efficiency.

Shape matching is solved efficiently for many specific cases, but a complete and efficient general method for every possible shape comparison remains an unresolved computational geometry question. This has real applications in computer vision and pattern recognition.

Information theory provides strong bounds on efficiency for many specific cases, but proving whether truly optimal encoding always exists for every possible scenario remains an unresolved theoretical question. This connects mathematics directly to modern data compression and communication.
